Description
本発明は、高濃度金属イオン含有水の製造方法およびキット、ならびに高濃度金属イオンを用いた消毒、抗菌または消臭剤に関する。 The present invention relates to a method and kit for producing water containing high-concentration metal ions, and a disinfectant, antibacterial or deodorant using high-concentration metal ions.
近年、銀イオンなどの金属イオンの殺菌・抗菌・消臭効果が社会的にも認知されてきている。高濃度の銀イオン水を得るために硝酸銀が一般的に用いられているが、硝酸銀は生体に対する刺激が強いので、この方法で得た銀イオン水をヒトや動物に適用する殺菌・抗菌・消臭剤に配合することはできない。かかる状況下、本発明者らは、徐崩壊性銀担持セラミックを開発し、水道水に約24時間浸漬するだけで約0.2ppm(約200ppb)の銀イオン水を作製することに成功している(特許文献1参照)。 In recent years, the bactericidal, antibacterial and deodorizing effects of metal ions such as silver ions have been recognized socially. Silver nitrate is generally used to obtain high-concentration silver ion water, but silver nitrate is highly irritating to living organisms. Cannot be mixed with odorants. Under such circumstances, the present inventors have developed a slowly-disintegrating silver-carrying ceramic and succeeded in producing about 0.2 ppm (about 200 ppb) of silver ion water by just immersing in tap water for about 24 hours. (See Patent Document 1).
しかし、殺菌・抗菌・消臭効果を高めるためにはさらに銀イオン濃度を高める必要がある。しかも、硝酸銀などの刺激の強い薬剤を用いた場合には、ヒトをはじめとする動物への適用に危険性と不安がある。 However, it is necessary to further increase the silver ion concentration in order to enhance the bactericidal, antibacterial and deodorizing effects. Moreover, when a highly irritating drug such as silver nitrate is used, there is a danger and anxiety in application to animals such as humans.
また、銀イオンを含有するゼオライト等から銀イオンを水中に抽出する試みがなされているが(特許文献2参照)、この方法はpH2〜5の酸性条件下で行われ、折角抽出された銀イオンが酸化銀として沈殿してしまい、実用的な消毒、抗菌または消臭剤を作製することはできなかった。 In addition, attempts have been made to extract silver ions into water from zeolite containing silver ions (see Patent Document 2). This method is carried out under acidic conditions of pH 2 to 5, and the extracted silver ions are folded. Precipitated as silver oxide, and no practical disinfectant, antibacterial or deodorant could be produced.
かかる状況において、安全かつ効率よく高濃度金属イオン水を得る技術が切望されていた。 Under such circumstances, a technique for obtaining high-concentration metal ion water safely and efficiently has been desired.
本発明の解決課題は、安全に高濃度金属イオン水を得る技術を提供することであった。 The problem to be solved by the present invention was to provide a technique for safely obtaining high-concentration metal ion water.
本発明者らは、上記課題を解決せんと鋭意研究を重ね、徐崩壊性銀担持セラミックを浸漬した水にモンモリロナイトやコロイダルシリカ等の粘土物質を添加することにより、ppmオーダーの銀イオン水を作製できることを見出した。本発明者らは、銅イオンなどの他の金属イオンにおいても同様に高濃度金属イオン水を作製できることを見出した。しかも本発明者らは、上記方法によれば、従来のような酸性条件下でなくてもppmオーダーの高濃度金属イオン水を作製できることを見出した。そしてこれらの知見から、本発明者らは本発明を完成させた。 The inventors of the present invention have made intensive researches to solve the above-mentioned problems, and prepared silver ion water in the order of ppm by adding clay substances such as montmorillonite and colloidal silica to water in which a slowly-disintegrating silver-carrying ceramic is immersed. I found what I can do. The present inventors have found that high concentration metal ion water can be similarly produced with other metal ions such as copper ions. In addition, the present inventors have found that according to the above method, high-concentration metal ion water in the order of ppm can be produced even under the conventional acidic conditions. Based on these findings, the present inventors have completed the present invention.

In the first aspect, the present invention provides the following:
(A) The following (i) to (iv):
(I) a metal-carrying inorganic compound carrying one or more metals selected from the group consisting of silver, gold, copper and zinc,
(Ii) clay material,
A fired product of a mixture comprising (iii) titanium dioxide, and (iv) a fine combustible material;

すなわち、本発明の金属イオン含有水の製造方法は、(a)の焼成物と、(b)の粘土物質と、(c)水とを混合することにより、銀、金、銅および亜鉛からなる群より選択される1種またはそれ以上の金属イオンを高濃度に含有する水溶液を得るものである。本発明者らは、(a)の焼成物を水に添加することによる、金属イオン含有水の製造方法を報告している(特開2007−332131号公報)。しかし、この方法で得られる金属イオン含有水中の金属イオン濃度はppbオーダーであった。それに対し、本発明によれば、約5ppmもの高濃度金属イオン濃度が達成される。その理由は、金属イオン含有水の製造時に粘土物質(b)を焼成物(a)と水(c)と共存させたためである。なお、焼成物(a)中の粘土物質(ii)は焼成されているのに対し、上記粘土物質(b)は焼成されていない点で異なる。 That is, the manufacturing method of the metal ion containing water of this invention consists of silver, gold | metal | money, copper, and zinc by mixing the baked material of (a), the clay substance of (b), and (c) water. An aqueous solution containing a high concentration of one or more metal ions selected from the group is obtained. The present inventors have reported a method for producing metal ion-containing water by adding the fired product of (a) to water (Japanese Patent Laid-Open No. 2007-332131). However, the metal ion concentration in the metal ion-containing water obtained by this method was on the order of ppb. In contrast, according to the present invention, metal ion concentrations as high as about 5 ppm are achieved. The reason is that the clay material (b) coexists with the fired product (a) and water (c) during the production of the metal ion-containing water. The clay material (ii) in the fired product (a) is fired, whereas the clay material (b) is not fired.
(a)の焼成物は、(i)銀、金、銅および亜鉛からなる群より選択される1種またはそれ以上の金属を担持してなる金属担持無機化合物、(ii)粘土物質、(iii)二酸化チタン、および(iv)微細可燃物を含む。 The fired product of (a) comprises (i) a metal-supported inorganic compound carrying one or more metals selected from the group consisting of silver, gold, copper and zinc, (ii) a clay material, (iii) ) Titanium dioxide, and (iv) fine combustibles.
金属担持無機化合物(i)は、抗菌性を発現するもととなる金属、例えば銀、金、銅または亜鉛のいずれかあるいはそれらのうち2種以上を担持してなり、これらの金属イオンの放出源となるものである。担体となる無機化合物としては、例えば、金属酸化物や金属リン酸塩などの金属塩等を主成分とする無機化合物材料が挙げられ、金属を担持することができる機能を有するものであれば、特に制限されるものではなく、上記以外にも、例えばセメント、石こう、ガラス系材料といった無機系の材料も挙げられる。これらのうちでも、金属担持無機化合物(i)としては、銀イオンを強固に長期間保持できることから、難溶性オルトリン酸塩に銀を担持してなる材料(例えば、特開平5−294808号公報、および特開平7−316008号公報参照。)などを好適に用いることができるが、これらに限定されるものではない。金属担持無機化合物(i)における金属の含有割合は、安定的にこれらの金属を担持させることができ、かつ十分な抗菌性能を発現することができる量に適宜調整すればよく、特に制限されるものではない。金属担持無機化合物(i)は、混練するその他の材料成分:(ii)粘土物質、(iii)二酸化チタン、および(iv)微細可燃物との均一混合性や、金属イオンの放出性能の観点から、粉末状または微粒子状であることが好ましい。 The metal-supported inorganic compound (i) carries a metal that exhibits antibacterial properties, such as silver, gold, copper, or zinc, or two or more of them, and releases these metal ions. It is a source. Examples of the inorganic compound serving as a carrier include inorganic compound materials mainly composed of metal salts such as metal oxides and metal phosphates, and the like, as long as they have a function capable of supporting a metal. There is no particular limitation, and in addition to the above, inorganic materials such as cement, gypsum, and glass-based materials are also included. Among these, as the metal-supported inorganic compound (i), since silver ions can be held firmly for a long period of time, a material obtained by supporting silver on a hardly soluble orthophosphate (for example, JP-A-5-294808, And JP-A-7-316008) can be preferably used, but is not limited thereto. The metal content in the metal-supported inorganic compound (i) may be appropriately adjusted to an amount capable of stably supporting these metals and exhibiting sufficient antibacterial performance, and is particularly limited.

For example, it can be defined as a substance consisting of particles of several microns to several tens of microns and including at least one of silica and alumina. It can also be defined as a substance that contains a silicate mineral as a main component, includes calcite, dolomite, feldspar, zeolite, and the like, and is solidified by firing to become a shell that forms the skeleton of the fired product. Examples of the clay material (ii) include, but are not limited to, Kibushi clay, Sasame clay, or Laponite RDS clay, zeolitic clay, LUDOX, water glass, montmorillonite, colloidal silica, bentonite and the like. It is not a thing. Two or more clay materials may be mixed and used. The clay material (ii) is preferably in the form of a powder from the viewpoint of uniform mixing with the components (i), (iii) and (iv).
二酸化チタン(iii)は、前記の金属イオンとともに、抗菌性を発現するものである。すなわち、前記の金属イオンのみでは、例えば、ベロ毒素、エンテロトキシン等といった菌放出毒素に対しては充分な抗菌効果を発現しにくかったが、二酸化チタンを含有させることにより、紫外線が当たることで光触媒効果が発現し、これらの菌放出毒素をも分解無害化することができる。二酸化チタン(iii)は、光触媒用として一般的に用いられる微粒子状のものが好ましい。 Titanium dioxide (iii) exhibits antibacterial properties together with the metal ions. That is, with the above metal ions alone, for example, it was difficult to express sufficient antibacterial effect against bacteria-release toxins such as verotoxin, enterotoxin, etc., but by containing titanium dioxide, photocatalytic effect was obtained by exposure to ultraviolet rays. Is expressed, and these fungus-release toxins can also be decomposed and detoxified. Titanium dioxide (iii) is preferably in the form of fine particles generally used for photocatalysts.
微細可燃物(iv)は、前記(i)〜(iii)成分とともに混練、成形した組成物を焼成した際に、焼失し、そのあとが空隙となることで、焼成物を多孔質体とする機能を有するものである。微細可燃物(iv)としては、焼成により焼失するものであれば、特に制限されるものではないが、粉末状若しくは粒状とした合成高分子、粉末状若しくは粒状とした天然木質材、粉末状若しくは粒状とした種子、合成繊維、天然繊維、活性炭繊維などが好適に用いることができる。粉末状もしくは粒状とした種子としては、例えば、胡桃を粉末状若しくは粒状にしたものなどを挙げることができるが、これらに限定されるものではない。更なる高いレベルの安全性を確保し、より安心して使用するためには、天然繊維または粉末状もしくは粒状の種子などを用いることが特に好ましい。微細可燃物(iv)は、抗菌剤に偏りのない空隙を生じさせて均一な多孔質体とするために、粉末状若しくは粒状又は繊維状であることが好ましい。例えば、成分(iv)が粒状である場合には、そのサイズは特に限定されないが、焼成物に徐崩壊性を持たせる場合には50〜500μm程度であることが好ましい。 The fine combustible material (iv) is burned off when the composition kneaded and molded together with the components (i) to (iii) is fired, and then becomes voids, thereby making the fired product a porous body. It has a function. The fine combustible material (iv) is not particularly limited as long as it is burned off by firing, but is not limited to a synthetic polymer in the form of powder or granule, natural wood material in the form of powder or granule, powder or Granulated seeds, synthetic fibers, natural fibers, activated carbon fibers and the like can be suitably used. Examples of powdered or granular seeds include, but are not limited to, those in which walnuts are powdered or granular. In order to ensure a further high level of safety and to use it with more peace of mind, it is particularly preferable to use natural fibers or powdered or granular seeds. The fine combustible material (iv) is preferably in the form of powder, granules, or fibers in order to create a uniform porous body by generating uniform voids in the antibacterial agent. For example, when the component (iv) is granular, the size is not particularly limited, but is preferably about 50 to 500 μm when the fired product has a slow disintegrating property.
成分(i)〜(iv)成分を含有してなる組成物は、抗菌剤に求められる適度な強度と優れた抗菌性能を付与するために、各成分の混合割合を以下のような割合とすることが好ましい。すなわち、金属担持無機化合物(i)は、金属イオンを放出して消臭抗菌性能を発現する抗菌剤における主要成分であり、抗菌剤の単位体積当りの抗菌性能を優れたものとするために、前記組成物中に、50〜74重量%程度とすることが好ましい。また、粘土物質(ii)は、抗菌剤の骨格を形成する成分であり、抗菌剤に求められる徐崩壊性を付与する場合には、前記組成物中に20〜44重量%程度とすることが好ましい。さらに、二酸化チタン(iii)は、成分(i)とともに、抗菌性能を発現する成分であり、組成物中に1〜10重量%程度とすることが好ましい。また、微細可燃物(iv)は、抗菌剤に偏りのない空隙を生じさせて多孔質体とするために、組成物中に5〜10重量%程度とすることが好ましい。さらに、成分(i)〜(iv)を含有してなる組成物には、例えば、CMC、メチルセルロースおよびアラビアガム等といったバインダー成分および水を少量加えてもよく、その添加量は、混練、成形時の取り扱い性を考慮して適宜決定すればよいが、前記バインダー成分は前記組成物中に0.5〜2重量%程度とするのが好ましい。 The composition comprising the components (i) to (iv) has a mixing ratio of each component as described below in order to impart an appropriate strength required for the antibacterial agent and excellent antibacterial performance. It is preferable. That is, the metal-supported inorganic compound (i) is a main component in the antibacterial agent that releases metal ions and exhibits deodorant antibacterial performance, and in order to make the antibacterial performance per unit volume of the antibacterial agent excellent. In the composition, it is preferably about 50 to 74% by weight. The clay substance (ii) is a component that forms the skeleton of the antibacterial agent, and in the case of imparting the slow disintegration required for the antibacterial agent, the clay material (ii) may be about 20 to 44% by weight in the composition. preferable. Furthermore, titanium dioxide (iii) is a component that exhibits antibacterial performance together with component (i), and is preferably about 1 to 10% by weight in the composition. In addition, the fine combustible material (iv) is preferably about 5 to 10% by weight in the composition in order to produce a non-biased void in the antibacterial agent to form a porous body. Furthermore, a small amount of binder components such as CMC, methylcellulose and gum arabic and water may be added to the composition comprising components (i) to (iv). However, the binder component is preferably about 0.5 to 2% by weight in the composition.
成分(i)〜(iv)を含有してなる組成物を混練するには、一般的な混練機を用いることができる。また、混練したものを成形する際の形状は、抗菌剤の用途に応じて適宜定めればよく、特に制限されるものではないが、表面積をより大きくして粘土物質(b)および水(c)との接触面積を確保しつつ、強度も損なわないものとすることが好ましい In order to knead the composition comprising the components (i) to (iv), a general kneader can be used. Further, the shape of the kneaded product when it is molded may be appropriately determined according to the use of the antibacterial agent, and is not particularly limited, but the surface area is increased to increase the clay material (b) and water (c It is preferable that the strength is not impaired while ensuring the contact area with
成分(i)〜(iv)を含有してなる組成物を混練、成形したものを焼成するときの条件としては、約500〜約800℃の雰囲気温度において2〜8時間焼成することが好ましい。ここでいう焼成とは、成形した材料に直接着火させ反応させるものではなく、炉内において高温でじっくりと処理することをいう。とくに本発明では徐崩壊性を与えるために、この温度管理に注意する必要があり、高温度、例えば900℃以上で焼成したものは徐崩壊性を失い、また500℃未満で焼成した時には脆くなりすぎる恐れがある。なお、前記焼成温度と焼成時間との関係は、焼成炉の熱容量との関係もあり、一概に規定することはできないが、前記温度および時間の範囲内で、焼成温度が500℃に近くなる低い温度で焼成する場合には焼成時間を長くとり、反対に焼成温度が800℃に近くなる高い温度で焼成する場合には焼成時間は短めにすることが、焼成物の強度と崩壊性との兼ね合いの観点から好ましい。 As conditions for firing the kneaded and molded composition containing the components (i) to (iv), it is preferable to fire at an ambient temperature of about 500 to about 800 ° C. for 2 to 8 hours. Firing here does not directly ignite and react the molded material, but means that the material is carefully treated at a high temperature in a furnace. In particular, in the present invention, it is necessary to pay attention to this temperature control in order to give slow disintegration, and those that are fired at a high temperature, for example, 900 ° C. or more lose their slow disintegration, and become brittle when fired at less than 500 ° C. There is a risk of too much. The relationship between the firing temperature and the firing time is also related to the heat capacity of the firing furnace, and cannot be generally specified, but within the range of the temperature and time, the firing temperature is close to 500 ° C. When firing at a temperature, the firing time is lengthened. On the contrary, when firing at a high temperature where the firing temperature is close to 800 ° C., shortening the firing time is a balance between the strength and the disintegration of the fired product. From the viewpoint of
かくして得られた焼成物は、抗菌性を発現するもととなる金属イオンの溶出源として作用する。焼成物は棒状、球状、顆粒、ペレット、粉末など様々な形態とすることができ、焼成物には適宜穴が設けられて金属イオンの溶出を促進するようになっていてもよい。取り扱いやすさ、金属イオンの溶出し易さなどの観点から、ペレット状、顆粒状または粉末状が好ましくい。 The fired product thus obtained acts as an elution source of metal ions that are the basis for developing antibacterial properties. The fired product can be in various forms such as rods, spheres, granules, pellets, and powders, and the fired product may be appropriately provided with holes to facilitate elution of metal ions. From the viewpoints of ease of handling, elution of metal ions and the like, a pellet, granule or powder is preferred.

For example, it can be defined as a substance consisting of particles of several microns to several tens of microns and including at least one of silica and alumina. It can also be defined as a substance that contains a silicate mineral as a main component, includes calcite, dolomite, feldspar, zeolite, and the like, and is solidified by firing to become a shell that forms the skeleton of the fired product. Examples of clay materials (b) include, but are not limited to, Kibushi clay, Sasame clay, or Laponite RDS clay, zeolitic clay, LUDOX, water glass, montmorillonite, colloidal silica, bentonite, and the like. It is not a thing. Two or more clay materials may be mixed and used. The clay substance (b) is preferably in the form of powder or fine particles from the viewpoint of uniform mixing of the fired product of (a) and (c) water. The clay material (b) may be of the same type as the clay material (ii) described above, or may be of a different type.

本発明の金属イオン含有水の製造方法は、焼成物(a)、粘土物質(b)および水(c)を混合することにより実施される。例えば、粘土物質(b)を分散させた水(c)に焼成物(a)を添加することにより金属イオン含有水を得てもよい。「金属イオン含有水」とは金属、例えば銀、金、銅、亜鉛などの抗菌性または殺菌性を有する金属イオンを含む水溶液をいう。また例えば、焼成物(a)と粘土物質(b)を混合したものに水(c)を添加することにより金属イオン含有水を得てもよい。また例えば、水(c)に焼成物(a)および粘土物質(b)を同時または順次添加してもよい。本発明の金属イオン含有水の製造方法の具体例は、焼成物(a)、粘土物質(b)および水(c)を混合することができれば、上記のものには限定されず、状況に応じて変更することができる。 The method for producing metal ion-containing water of the present invention is carried out by mixing the fired product (a), the clay material (b), and water (c). For example, metal ion-containing water may be obtained by adding the fired product (a) to water (c) in which the clay substance (b) is dispersed. “Metal ion-containing water” refers to an aqueous solution containing metal, for example, metal ions having antibacterial or bactericidal properties such as silver, gold, copper, and zinc. Further, for example, water containing metal ions may be obtained by adding water (c) to a mixture of the fired product (a) and the clay material (b). Further, for example, the fired product (a) and the clay material (b) may be added simultaneously or sequentially to the water (c). Specific examples of the method for producing metal ion-containing water of the present invention are not limited to the above as long as the fired product (a), the clay material (b) and the water (c) can be mixed. Can be changed.
本発明における金属イオン含有水の製造時における焼成物(a)、粘土物質(b)および水(c)の混合物中の焼成物(a)の量は、必要とされる金属イオン含有水中の金属イオン濃度に応じて適宜増減することができる。 The amount of the calcined product (a) in the mixture of the calcined product (a), the clay material (b) and the water (c) at the time of producing the metal ion-containing water in the present invention is the required metal in the metal ion-containing water. It can be appropriately increased or decreased depending on the ion concentration.
上記混合物中の粘土物質(b)の量が多ければ多いほど、焼成物(a)からの金属イオンの溶出量が多くなるが、得られる金属イオン含有水の透明度が低下する。上記混合物中の好ましい粘土物質(b)の濃度は0.1〜5重量%程度を目安とするが、焼成物(a)の量、必要な金属イオン濃度、適用箇所、適用目的などの諸条件により適宜変更することができる。 As the amount of the clay substance (b) in the mixture increases, the amount of metal ions eluted from the fired product (a) increases, but the transparency of the resulting metal ion-containing water decreases. The concentration of the preferred clay substance (b) in the mixture is about 0.1 to 5% by weight, but various conditions such as the amount of the fired product (a), the required metal ion concentration, the application location, the application purpose, etc. Can be changed as appropriate.
本発明において好ましい金属は銀、金、銅、亜鉛などの抗菌性または殺菌性を有する金属であり、なかでも銀および銅が好ましく、特に銀が好ましい。 In the present invention, preferred metals are antibacterial or bactericidal metals such as silver, gold, copper, and zinc, among which silver and copper are preferred, and silver is particularly preferred.
金属イオン含有水を使用する約3時間前〜数日前に、本発明のこの態様の方法により金属イオン含有水を作製しておくことが好ましい。 It is preferable to prepare metal ion-containing water by the method of this aspect of the present invention about 3 hours to several days before using metal ion-containing water.
本発明の金属イオン含有水の製造方法において、焼成物(a)を複数回繰り返し使用することもできる。例えば、粘土物質(b)を含む水(c)に焼成物(a)を添加して金属イオン抽出を行った後、焼成物(a)を回収して、新たに粘土物質(b)を含む水(c)に添加する操作を繰り返して、金属イオン抽出を複数回行うこともできる。 In the method for producing metal ion-containing water of the present invention, the fired product (a) can be used repeatedly a plurality of times. For example, after adding the calcined product (a) to the water (c) containing the clay material (b) and extracting the metal ions, the calcined product (a) is recovered and newly contains the clay material (b). By repeating the operation of adding to water (c), metal ion extraction can be performed a plurality of times.

酸性条件下での金属イオンの溶出は、金属塩の沈殿を引き起こし、かえって水中の金属イオン濃度を低下させることが知られている。しかし本発明においては、焼成物(a)、粘土物質(b)および水(c)の混合を比較的強い酸性条件下で行わなくても、粘土物質(b)が水中に共存することにより、ppmオーダーという十分な量の金属イオンを水中に溶出させることができ、しかも金属塩の沈殿を防止することができる。したがって、本発明においては、焼成物(a)、粘土物質(b)および水(c)の混合をpH5よりも高いpHの条件下、好ましくはpH約5.5以上、より好ましくはpH約6以上、さらに好ましくはpH約6〜約8、最も好ましくはpH約6.5〜約7.5の条件下で行う。本発明において水(c)として純水や水道水を用いた場合は、pHが約6.5〜約7.5の範囲となる場合が多い。 It is known that elution of metal ions under acidic conditions causes precipitation of metal salts, which in turn decreases the metal ion concentration in water. However, in the present invention, the clay material (b) coexists in water without mixing the fired product (a), the clay material (b) and the water (c) under relatively strong acidic conditions. A sufficient amount of metal ions on the order of ppm can be eluted in water, and precipitation of metal salts can be prevented. Therefore, in the present invention, the mixture of the calcined product (a), the clay material (b) and the water (c) is subjected to a pH condition higher than pH 5, preferably about pH 5.5 or more, more preferably about pH 6. More preferably, the reaction is performed under conditions of pH of about 6 to about 8, and most preferably pH of about 6.5 to about 7.5. In the present invention, when pure water or tap water is used as the water (c), the pH is often in the range of about 6.5 to about 7.5.
本発明において、焼成物(a)は棒状、球状、筒状、顆粒、ペレット、粉末など様々な形態とすることができるが、焼成物(a)が直径5mm以下、好ましくは直径3mm以下、より好ましくは直径2mm以下の粒状物または粉末である場合には、より高濃度の金属イオン水をより短時間のうちに得ることができる。本発明の使用目的に応じてペレットの形状やサイズを選択して、金属イオンを徐々に放出、繰り返し放出、あるいは素早く放出させることができる。これらのことは、以下に述べる本発明の諸態様においてもあてはまる。 In the present invention, the fired product (a) can have various forms such as rods, spheres, cylinders, granules, pellets, and powders, but the fired product (a) has a diameter of 5 mm or less, preferably 3 mm or less. In the case of a granular material or powder preferably having a diameter of 2 mm or less, a higher concentration of metal ion water can be obtained in a shorter time. The shape and size of the pellet can be selected according to the purpose of use of the present invention, and metal ions can be released gradually, repeatedly, or quickly. These also apply to the embodiments of the present invention described below.

(1) Preparation of fired product 60% by weight of a metal-supporting inorganic compound (Silver Ace, manufactured by Taihei Chemical Industrial Co., Ltd.), which is a material formed by supporting 10% by weight of silver on two or more kinds of hardly soluble orthophosphates of metals. 30% by weight of Kibushi clay, 1% by weight of titanium dioxide (manufactured by Teika Co., Ltd., AMT-100) and activated carbon powder (manufactured by Taihei Chemical Sangyo Co., Ltd., cocool SS (particle size 75-250 μm) About 97% by weight))) After kneading the composition consisting of 9% by weight and forming into a pellet (size: cylinder with a diameter of 1.5 cm and a length of 1.5 cm), A fired product was prepared by firing for 2 hours. The weight per baked pellet was about 2 g, and the silver content per pellet was about 125 mg.
(2)粘土物質(RDS)が銀イオン濃度に及ぼす影響
上で得られた焼成物ペレット1個または5個を、0.01重量%から5重量%までのRDS(Laporte Inorganics社製)を分散させた水道水500mlに投入し、24時間後に水中の銀イオン濃度を測定した(n=3)。なお、水温は室温とし、pHは調節しなかった。溶液のpHは6.8〜7.3であった。銀イオン濃度の測定は、ICP−AES分光装置(「RIGAKU CIROS CCD」、(株)リガク製)を用いて行った。結果を図1の左パネルに示す。RDS濃度の上昇とともに、水中に溶出してくる銀イオン濃度が上昇する傾向が見られた。5重量%のRDSが水中に存在する場合、銀イオン濃度は4.879ppmであった。
(2) Effect of clay material (RDS) on silver ion concentration Disperse one or five calcined pellets obtained above from 0.01 wt% to 5 wt% RDS (Laporte Inorganics) It poured into 500 ml of let tap water, and the silver ion concentration in water was measured 24 hours later (n = 3). The water temperature was room temperature and the pH was not adjusted. The pH of the solution was 6.8-7.3. The silver ion concentration was measured using an ICP-AES spectrometer (“RIGAKU CIROS CCD”, manufactured by Rigaku Corporation). The results are shown in the left panel of FIG. As the RDS concentration increased, the concentration of silver ions eluted in water tended to increase. When 5 wt% RDS was present in water, the silver ion concentration was 4.879 ppm.
水中RDS濃度を1重量%とし、上で得られた焼成物ペレット1個または5個を投入することにより、水中銀イオン濃度の経時変化を調べた。他の実験条件は上で述べたのと同じであった。結果を図1の右パネルに示す。ペレット1個、5個いずれの場合にも、経時的に水中銀イオン濃度が上昇する傾向が見られた。特にペレット5個を投入した場合、水中銀イオン濃度は48時間後に約3.5ppmに達した。 The time-dependent change of the silver ion concentration in water was examined by setting the RDS concentration in water to 1% by weight and introducing one or five calcined pellets obtained above. Other experimental conditions were the same as described above. The results are shown in the right panel of FIG. In either case of 1 pellet or 5 pellets, the silver ion concentration in water tended to increase over time. In particular, when 5 pellets were charged, the silver ion concentration in water reached about 3.5 ppm after 48 hours.
(3)水中の粘土物質の種類の影響
水中の粘土物質として各0.1重量%のRDS(Laporte Inorganics社製)、LUDOX(Sigma社製)または水ガラス(ナカライテクノス製)を用い、上記ペレットを1個または5個を用いて上と同様の実験を行い、3日目および7日目に水中の銀イオン濃度を測定した。溶液のpHは6.8〜7.3であった。結果を表1に示す。
(3) Influence of the type of clay material in water Each of the above pellets using 0.1% by weight of RDS (manufactured by Laporte Inorganics), LUDOX (manufactured by Sigma) or water glass (manufactured by Nacalai Technos) as the clay material in water. The same experiment as above was carried out using 1 or 5 of each, and the silver ion concentration in water was measured on the 3rd and 7th days. The pH of the solution was 6.8-7.3. The results are shown in Table 1.
いずれの粘土物質が水中に存在する場合にも、ペレットの個数および日数の増加に伴って、水中の銀イオン濃度が上昇する傾向が見られた。水ガラス(ペレット5個)の場合に銀イオン濃度が若干低い傾向はあるものの、銀イオン濃度は水中の粘土物質の種類にはあまり影響されないことがわかった。 Even when any clay material was present in water, the silver ion concentration in water tended to increase as the number of pellets and the number of days increased. In the case of water glass (5 pellets), the silver ion concentration tended to be slightly lower, but the silver ion concentration was found to be less affected by the type of clay material in the water.
対照実験として、水中に粘土物質が存在しない条件下で上と同様の実験を行い、水中の銀イオン濃度を調べた。実験には上記ペレット1個または5個を用い、経時的に銀イオン濃度を測定した。溶液のpHは6.8〜7.3であった。結果を図2に示す。ペレット数を5個まで増加させても相加的に銀イオン濃度は上昇しなかった。ペレット5個を投入し、14日後に約0.8ppmの銀イオン濃度となったが、粘土物質が水中に共存する場合の実施例1のような高濃度の銀イオン濃度(約5ppm)は達成されなかった。 As a control experiment, an experiment similar to the above was performed under the condition that no clay substance was present in water, and the silver ion concentration in water was examined. In the experiment, one or five of the above pellets were used, and the silver ion concentration was measured over time. The pH of the solution was 6.8-7.3. The results are shown in FIG. Even when the number of pellets was increased to 5, the silver ion concentration did not increase additively. Five pellets were added and the silver ion concentration reached about 0.8 ppm after 14 days. However, a high silver ion concentration (about 5 ppm) as in Example 1 when the clay material coexists in water was achieved. Was not.
高濃度銀イオン水の抗菌効果について、大腸菌(ATCC25922)、ブドウ球菌(ATCC29213)、緑膿菌(ATCC27853)を用いて調べた。
各サンプル溶液15mlを50mlの遠沈管に入れ、それぞれの溶液に各菌液を100マイクロリットル(108cfu/ml)添加し、よく混和した。菌液添加0、5、15、30分時に菌液を混和した溶液から100マイクロリットルサンプリングし、滅菌シャーレ(直径9cm)に移した。あらかじめ準備しておいた標準寒天培地液(ニッスイ:日水製薬株式会社、Tokyo、Japan)10mlをシャーレに入れ、サンプリング液と混和した。その後、シャーレを37℃の恒温器内で24時間インキュベートした。24時間後、シャーレ内のコロニー数をカウントした。結果を表2に示す。
The antibacterial effect of high-concentration silver ion water was examined using Escherichia coli (ATCC 25922), Staphylococcus (ATCC 29213), and Pseudomonas aeruginosa (ATCC 27853).
15 ml of each sample solution was put into a 50 ml centrifuge tube, and 100 microliters (10 8 cfu / ml) of each bacterial solution was added to each solution and mixed well. At 0, 5, 15, and 30 minutes after addition of the bacterial solution, 100 microliters were sampled from the solution mixed with the bacterial solution and transferred to a sterile petri dish (diameter 9 cm). 10 ml of a standard agar medium solution (Nissui: Nissui Pharmaceutical Co., Ltd., Tokyo, Japan) prepared in advance was placed in a petri dish and mixed with the sampling solution. Thereafter, the petri dish was incubated in a 37 ° C. incubator for 24 hours. After 24 hours, the number of colonies in the petri dish was counted. The results are shown in Table 2.
粘土物質LUDOXが水中に存在する条件下で得られた銀イオン水を用いた場合(LUDOXの欄)は、粘土物質が水中に存在しない条件下で得られた銀イオン水を用いた場合(ミラクルアクア)に比べて、大腸菌、ブドウ球菌、緑膿菌のいずれに対しても強力な抗菌効果が得られた。これは粘土物質LUDOXが水中に存在する条件下で得られた銀イオン水の銀イオン濃度が高いためであると考えられた。表2のControlは水だけの場合である。 When silver ion water obtained under the condition where the clay substance LUDOX exists in water (LUDOX column) is used when silver ion water obtained under the condition where the clay substance does not exist in water (Miracle) Compared to Aqua), a strong antibacterial effect was obtained against all of Escherichia coli, Staphylococcus and Pseudomonas aeruginosa. This was considered to be because the silver ion concentration of the silver ion water obtained under the condition that the clay substance LUDOX exists in water was high. Control in Table 2 is for water only.
銅を担持するペレットを用いた場合の銅イオン溶出について調べた。銅担持ペレットは以下のようにして作製した。
シラスバルーンと硝酸銅を重量比で1:1に混和したもの(A)60重量%と、木節粘土(B)30重量%と、二酸化チタン(テイカ株式会社製、AMT−100)(C)1重量%と、微細可燃物として活性炭粉末(太平化学産業株式会社製、ヤシコールSS(粒径75〜250μmのもの約97重量%))(D)9重量%とからなる組成物を混練し、ペレット状(サイズ:直径1.5cm、長さ2.0cmの筒状)に成形した後に、700℃前後の雰囲気温度において約2時間焼成することにより、焼成物を作製した。
The elution of copper ions when using a pellet carrying copper was investigated. The copper-carrying pellet was produced as follows.
A mixture of Shirasu balloon and copper nitrate in a weight ratio of 1: 1 (A) 60% by weight, Kibushi clay (B) 30% by weight, titanium dioxide (AMT-100, manufactured by Teika Co., Ltd.) (C) 1% by weight and a composition consisting of activated carbon powder (made by Taihei Chemical Sangyo Co., Ltd., cocool SS (about 97% by weight with a particle size of 75 to 250 μm)) (D) 9% by weight as a fine combustible material, After forming into a pellet shape (size: cylindrical shape having a diameter of 1.5 cm and a length of 2.0 cm), the fired product was produced by firing at an ambient temperature of around 700 ° C. for about 2 hours.
作製したペレット1個の重量は2g、ペレット1個あたりの銅含量は60mgであった。水中の粘土物質としてLUDOXを用いて実験を行った。ペレット1個を24時間または48時間浸漬後に銅イオン濃度を測定した。溶液のpHは6.8〜7.3であった。その他の実験条件は実施例1で述べたとおりであった。結果を表3に示す。 The weight of one produced pellet was 2 g, and the copper content per pellet was 60 mg. Experiments were performed using LUDOX as the clay material in water. After immersing one pellet for 24 hours or 48 hours, the copper ion concentration was measured. The pH of the solution was 6.8-7.3. Other experimental conditions were as described in Example 1. The results are shown in Table 3.
水中に粘土物質が存在しない場合と比べて、水中に粘土物質が存在する場合に銅イオン溶出量が3.5〜6倍に増加し、水中の粘土物質の効果が確認された。 Compared with the case where no clay substance exists in water, the elution amount of copper ions increased 3.5 to 6 times when the clay substance existed in water, and the effect of the clay substance in water was confirmed.
金属担持焼成物の粒径を小さくして、金属イオン溶出速度および量について調べた。実施例1で作製した銀担持ペレットをそのまま、あるいは乳鉢内で直径1〜2mmに粉砕したものを、水道水またはLUDOX含有水道水にて抽出し、銀イオン濃度を経時的に測定した。溶液のpHは6.8〜7.3であった。結果を表4に示す。
金属担持焼成物の粒径を小さくすることによって、金属イオンの溶出が素早くなり、濃度も高くなった。 By reducing the particle size of the metal-supported fired product, elution of metal ions was quickened and the concentration was increased.
本発明は、消臭剤や抗菌剤などに応用することができるので、日用品や医薬品の分野ならびに畜産などの分野において利用可能である。 Since the present invention can be applied to deodorants, antibacterial agents, and the like, it can be used in the fields of daily necessities and pharmaceuticals, and livestock.
