It was difficult to do. For example, although zeolite differs depending on the type, the crystal structure can be kept stable under the conditions of a heat-resistant temperature of about 700 to 800 ° C. and a pH of 3 to L1. Hyde mouth talcite has a temperature at which the crystal structure changes by dehydration is about 200 ° C, pH is a stable region of the crystal structure under the condition of 3 to 11.5, and alofene has a heat resistant temperature of 500 ° C, The pH range from 3 to 11 is a stable region of the crystal structure. Therefore, in order to perform molding while maintaining the adsorption characteristics of these adsorbents, it is necessary to establish a technique capable of performing the molding force within the range of the conditions described above.
[0007] これら吸着剤の従来の成形方法について以下に述べる。例えば、ゼォライトは当該 ゼォライト自身に自己粘結性がな!、ため、バインダー材料を加えて焼成体として成形 することが一般的である。このノ インダー材料としては、成形力卩ェ性を確保するため、 通常はカルボキシメチルセルロースやポリビュルアルコール等の有機結合剤が用い られ、また、これにシリカ、アルミナやカオリン等の無機材をカ卩えることが多い。ゼオラ イトの成形おいては、このようなバインダーを加えた混練物を乾燥させた後、焼成を 行う力 上述のようにゼォライトの耐熱温度により、少なくとも約 700〜800°C以下の 温度で焼成を行わなければならな 、。ゼォライトの成形にぉ 、てはこのように低温焼 成を行うため、大きな材料強度を得ることは難しぐさらに有機結合剤が残存し、細孔 の閉塞により吸着特性が低下してしまうという問題が生ずる。また、有機結合材を燃 焼させるためには数十時間の焼成が必要となるため、成形体の製造には大きなエネ ルギー消費を伴うことになる。 [0008] 一方、バインダー材料としてセメントを使用する常温のゼォライト成形方法力 従来 より提唱されて 、るが、このゼォライト成形方法によれば成形体は強アルカリ環境とな るためゼオライトが損傷してしまう虞がある。 [0007] Conventional molding methods for these adsorbents are described below. For example, since zeolite is not self-adhesive to the zeolite itself, it is generally formed into a fired body by adding a binder material. As this noder material, an organic binder such as carboxymethylcellulose or polybulualcohol is usually used in order to ensure molding strength, and an inorganic material such as silica, alumina, or kaolin is used as the binder material. Often. In the molding of zeolite, the kneaded material added with such a binder is dried and then fired. As described above, firing is performed at a temperature of at least about 700 to 800 ° C. or less depending on the heat resistant temperature of zeolite. Must be done. In the case of zeolite formation, since low-temperature sintering is performed in this way, it is difficult to obtain a large material strength. Furthermore, there is a problem that the organic binder remains, and the adsorption characteristics are deteriorated due to pore clogging. Arise. In addition, since the organic binder is burned for several tens of hours in order to burn it, a large amount of energy is consumed in the production of the molded body. [0008] On the other hand, the strength of a method for molding zeolite at room temperature using cement as a binder material. Conventionally, according to this method of molding zeolite, the molded article becomes a strong alkaline environment, and the zeolite is damaged. There is a fear.
[0009] また、石炭灰などシリカとアルミを含む廃棄物のリサイクル利用技術として注目を集 めている「人工ゼォライト」は、主として P型ゼオライトを含み、この P型ゼオライトの耐 熱温度は 300°C以下である。このため、従来力も用いられてきた焼成によるゼォライト 成形技術を適用できないことから、未だ有効な成形方法がなぐ多面的な用途に利 用し難いという問題があった。  [0009] “Artificial zeolite”, which is attracting attention as a recycling technology for waste containing silica and aluminum such as coal ash, mainly contains P-type zeolite, and the heat resistance temperature of this P-type zeolite is 300 °. C or less. For this reason, there has been a problem that it is difficult to use the multi-purpose applications that still have an effective molding method because the zeolit molding technology by firing, which has been used in the past, cannot be applied.
[0010] さらに、ァロフェンの成形に関する従来技術は、上述したゼォライトの成形と同様に 榭脂ゃ有機結合剤を用いた技術が殆どである。ァロフェンは耐熱温度が 500°Cとゼ オライトより低ぐ上述したゼォライトの成形と同様の問題が生ずる。  [0010] Further, most of the conventional techniques relating to the molding of alophene are techniques using an organic binder in the same manner as the above-described molding of zeolite. Alofen has a heat resistant temperature of 500 ° C, which is lower than that of zeolite.
[0011] また、例えばハイド口タルサイトや LDH (Layered Double Hydroxide)等の層状複水 酸ィ匕物に関しては、未だ有効な成形技術が確立されていないのが現状である。  [0011] Further, for layered double hydroxides such as Hyde mouth talcite and LDH (Layered Double Hydroxide), an effective molding technique has not been established yet.
[0012] このように、吸着特性を損なうことなく粉末状の吸着剤を成形することは従来技術で は困難であるため、これら吸着剤の吸着特性を損なわずに、所望の形状やサイズに 形を整え、さらに強度、耐水性及び多孔質性を付与することができる有効な成形技 術の確立が必要とされて 、る。  [0012] As described above, since it is difficult in the prior art to form a powdery adsorbent without impairing the adsorption characteristics, it is possible to form the adsorbent in a desired shape and size without impairing the adsorption characteristics of these adsorbents. Therefore, it is necessary to establish an effective molding technique capable of providing strength, water resistance and porosity.
[0013] 本発明は、以上の問題点を考慮してなされたもので、例えば水処理及びガス処理 用の成形体、室内環境浄化機能をもつ建材など様々な環境改善用途や産業用途に 供することができる吸着剤含有常温固化組成物と、これを用いた吸着剤含有成形体 、吸着剤含有建材及び舗装用注人材とを提案することを目的とする。  [0013] The present invention has been made in consideration of the above problems, and is used for various environmental improvement applications and industrial applications such as molded articles for water treatment and gas treatment, and building materials having a function of purifying indoor environment.

[0053] そして、得られた吸着剤含有常温固化組成物は、水及び遅延剤がそれぞれ所定 の割合で添加されて混練された後、適正な成形方法により成形され、さらに養生を行 うことにより常温で固化し、所望の形状やサイズでなる成形体又は建材 (すなわち、吸 着剤含有成形体又は吸着剤含有建材)となり得る。なお、固化に要する時間を調節 する遅延剤としては、クェン酸、多糖類、炭酸水素ナトリウム及びコンクリート用遅延 剤等の各種公知の遅延剤を適用することができる。  [0053] Then, the obtained adsorbent-containing room temperature solidifying composition is prepared by adding water and a retarder at a predetermined ratio and kneading, then molding by an appropriate molding method, and further curing. It can be solidified at room temperature to become a molded product or building material having a desired shape or size (that is, an adsorbent-containing molded product or an adsorbent-containing building material). As the retarder for adjusting the time required for solidification, various known retarders such as succinic acid, polysaccharides, sodium hydrogen carbonate and concrete retarders can be applied.
[0054] 本発明の吸着剤含有組成物では、組成として酸ィ匕マグネシウムと吸着剤とを含ん でいれば、酸ィ匕マグネシウムの水和と外気との接触による炭酸ィ匕により、吸着剤を常 温で固化することが可能である。この組成物にさらに無機硫酸化合物、無機炭酸ィ匕 合物及び無機リン酸化合物からなる群から選択される 1種又は 2種以上の化合物を 配合することにより、固化強度を向上させることができ、加えて以下に示すように pHコ ントロールが可能になる等の新たな効果を与えることができる。また、これらの組成物 に木節粘土、蛙目粘土、頁岩粘土、カオリン、ノ、ロイサイト、ベントナイト、酸性白土、 セピオライト及びァタノルジャイトからなる群力 選択される 1種又は 2種以上の可塑 性粘土の配合により可塑性や強度を向上させることができ、さらに水ガラス、カリ水ガ ラス、リチウム水ガラス、シリカゾル、珪酸ナトリウム、珪酸カリウム、珪酸リチウム又は シリカフュームを 0. 1〜5. 0質量％添加することで強度増加を図り、耐水性等を改善 することができる。  [0054] In the adsorbent-containing composition of the present invention, if the composition contains magnesium oxide and an adsorbent, the adsorbent is obtained by carbonic acid due to hydration of acid magnesium and contact with the outside air. It can be solidified at normal temperature. By further adding one or more compounds selected from the group consisting of inorganic sulfate compounds, inorganic carbonate compounds and inorganic phosphate compounds to this composition, the solidification strength can be improved, In addition, new effects such as enabling pH control as shown below can be provided. In addition, one or more plastic clays selected from the group power consisting of Kibushi clay, Sasame clay, Shale clay, Kaolin, Noh, Leucite, Bentonite, Acid clay, Sepiolite and Hutanorgite are included in these compositions. Addition of 0.1 to 5.0% by mass of water glass, potash water glass, lithium water glass, silica sol, sodium silicate, potassium silicate, lithium silicate, or silica fume. As a result, the strength can be increased and the water resistance and the like can be improved.
[0055] 本発明の吸着剤含有常温固化組成物は、混合した組成の化学反応より生じるマグ ネシゥムの硫酸化合物、リン酸化合物、炭酸化合物及び空気との接触、すなわち炭 酸ィ匕による炭酸水素化合物の形成による固化を原理とするため、基本的には PH11 以下の低アルカリ条件で成形が可能となる。しかしながら、陽イオン交換性の高いゼ オライトを成形しょうとする場合においては、イオン交換作用によりゼォライトに含まれ る Na等の金属イオンがスラリー内部に溶出し、高 pHになる現象が生じる。このため、 ゼォライトの成形にぉ 、ては、ただ単に前述の原料を配合するだけでは不十分であ り、 pHをコントロールする手段を講じなければならない。前に示したようにゼォライト のアルカリ側の pH安定条件により、短期的には 11. 5以下に pHを調整し、より好まし くは 11以下にする必要がある。 [0055] The adsorbent-containing room temperature solidifying composition of the present invention is a hydrogen carbonate compound produced by contacting magnesium sulfate compound, phosphate compound, carbonate compound and air resulting from the chemical reaction of the mixed composition, that is, carbonic acid salt. Basically, PH11 Molding is possible under the following low alkali conditions. However, when trying to mold zeolite with high cation exchange properties, metal ions such as Na contained in the zeolite elute into the slurry due to the ion exchange action, resulting in a high pH. For this reason, for the formation of zeolite, it is not sufficient to simply add the above-mentioned raw materials, and means for controlling the pH must be taken. As indicated above, the pH should be adjusted to 11.5 or less in the short term, more preferably 11 or less, depending on the pH stability conditions on the alkali side of zeolite.
[0056] pHの緩衝は可塑性粘土や pH緩衝剤を配合することにより行うことができる。ここで pH緩衝剤としては、硫酸や塩酸、硝酸等の無機酸を適用することができるが、酸性 の硫酸化合物であり硬化にも寄与するバインダー材料である硫酸第 1鉄、硫酸第 2鉄 、硫酸アルミニウム及び硫酸マグネシウムの使用が好ましい。なお、硬化が進行する とマグネシウムイオン、イオン交換により溶出した Na等のイオンが固化反応の進展や 炭酸ィ匕により固定されるため、 pHは低下する傾向を示す。  [0056] The pH can be buffered by adding plastic clay or a pH buffering agent. Here, inorganic acids such as sulfuric acid, hydrochloric acid, and nitric acid can be used as pH buffering agents. However, ferrous sulfate, ferric sulfate, which are acidic sulfuric compounds and contribute to curing, The use of aluminum sulfate and magnesium sulfate is preferred. As curing proceeds, magnesium ions and ions such as Na eluted by ion exchange are fixed by the progress of the solidification reaction and carbonic acid so that the pH tends to decrease.
[0057] また、ゼォライト成形における pHの緩衝は、酸化マグネシウムと、硫酸化合物、炭 酸化合物及びリン酸化合物との配合比により調整することができる。すなわち、酸ィ匕 マグネシウムの配合割合を小さくすることで pHを低下させることができ、さらに成形対 象のゼォライトを予め Ca型や Mg型等に変換を行うことで高 pHになることを防ぐこと ができる。  [0057] Further, the pH buffer in the zeolite molding can be adjusted by the blending ratio of magnesium oxide to a sulfate compound, a carbonate compound and a phosphate compound. In other words, the pH can be lowered by reducing the blending ratio of magnesium oxide and further preventing the formation of high pH by previously converting the zeolite to be molded into Ca type or Mg type. Can do.
[0058] ゼォライト以外のァロフィン、ィモゴライト、ハイド口タルサイト等の成形にぉ ヽても同 様の pH緩衝が必要となる力 これらの成形はゼオライトほど困難なものではな 、。  [0058] The force that requires the same pH buffering when molding alofin, imogolite, hydrated talcite, etc. other than zeolite, is not as difficult as zeolite.
[0059] ところで、この吸着剤含有常温固化組成物の固化及び成形は、配合される吸着剤 の表面性状に大きく影響され、強度、多孔質性及び硬化時間等が複雑に変化する。  By the way, solidification and molding of this adsorbent-containing room temperature solidified composition are greatly influenced by the surface properties of the adsorbent to be blended, and the strength, porosity, curing time, and the like change in a complicated manner.
[0060] 例えば、選択化合物と酸化マグネシウムと吸着剤とをそれぞれ所定の割合で配合 させた場合においても、当該吸着剤がァロフェン、ゼォライト又はハイド口タルサイトで ある場合には、成形体の強度、硬化時間、多孔質性及び耐水性等が全く異なるもの となるため、配合する吸着剤の種類に応じてバインダーとなる組成物を適宜調整する ことが必要となる。  [0060] For example, even when the selected compound, magnesium oxide, and the adsorbent are blended in a predetermined ratio, if the adsorbent is alophen, zeolite, or hyde mouth talcite, the strength of the molded body, Since the curing time, porosity, water resistance, and the like are completely different, it is necessary to appropriately adjust the composition serving as a binder according to the type of adsorbent to be blended.
[0061] ここで耐水性を向上させるには、吸着剤含有常温固化組成物に耐水性改善剤を添 加するが、この耐水性改善剤としては、珪酸ナトリウム、珪酸カリウム、珪酸リチウム又 はシリカゾルを 0. 1〜5. 0質量0 /0添加することが好ましぐ特に 0. 2〜2. 0質量0 /0添 カロすることがより好ましい。また、このほ力メチルトリエトキシシラン等のシラン系カップ リング剤も耐水性改善剤として用いることができる。 [0061] Here, in order to improve the water resistance, a water resistance improving agent is added to the adsorbent-containing room temperature solidifying composition. Pressurized Suruga, as the water resistance improving agent, sodium silicate, potassium silicate, 0.1 to 5 silica sol is lithium silicate also. 0 wt 0/0 is preferred instrument particularly adding 0.2 to 2.0 it is more preferable to mass 0/0 added Caro. In addition, a silane coupling agent such as methyltriethoxysilane can also be used as a water resistance improving agent.
[0062] 以上の構成において、無機硫酸化合物、無機炭酸化合物及び無機リン酸化合物 力 なる群力 選択される 1種又は 2種以上の化合物と、酸化マグネシウムと、吸着剤 とを所定の割合で配合した吸着剤含有常温固化組成物に、所定の水量及び遅延剤 を添加して混練することにより、常温で、かつ低アルカリ条件下で、焼成を行なうこと なく堅固で耐水性を有する吸着剤含有成形体を形成することができる。  [0062] In the above configuration, inorganic sulfate compound, inorganic carbonic acid compound and inorganic phosphate compound Power group strength One or two or more selected compounds, magnesium oxide, and adsorbent are blended at a predetermined ratio.

[0063] このように本発明の吸着剤含有成形体では、焼成を行なわずに常温で、かつ低ァ ルカリ条件下で固化するので、耐熱性及び耐アルカリ性が低く結晶構造が壊れ易 、 吸着剤であっても、この結晶構造を保持したまま成形することができる。  [0063] Thus, the adsorbent-containing molded article of the present invention is solidified at room temperature and under low alkali conditions without firing, so that the crystal structure is easily broken due to low heat resistance and alkali resistance. Even so, it can be molded while maintaining this crystal structure.

Example
[0087] 先ず初めに、酸化マグネシウムと、無機硫酸化合物、無機炭酸化合物、無機リン酸 化合物又は水ガラスとの組み合わせによる固ィ匕剤成分の強度について検証する。こ こで参考例 1〜6では、表 1に示す酸ィ匕マグネシウムと、無機硫酸化合物、無機炭酸 化合物、無機リン酸化合物とを用い、選択した所定の組成物粉体を所定の割合 (表 中の質量％)で配合した組成物を用いた。  First, the strength of the solidifying agent component obtained by combining magnesium oxide with an inorganic sulfate compound, an inorganic carbonate compound, an inorganic phosphate compound, or water glass will be verified. Here, in Reference Examples 1 to 6, a selected predetermined composition powder was added at a predetermined ratio (Table) using acid magnesium as shown in Table 1, an inorganic sulfate compound, an inorganic carbonate compound, and an inorganic phosphate compound. The composition blended in (mass% in the middle) was used.
[0088] 各参考例 1〜6毎に、表 1に示す各組成物粉体をポットミルで 1時間混練し、これに 表 1に示す含水率となる水及び遅延剤、水ガラスを添加してヘラで十分混練した後、 これをアクリル製型枠に充填して高さ 10mm、幅 10mm、長さ 70mmの成形体（サン プル)を得た。さらにこの成形体を密閉容器内にて 1週間室温で養生し、室内で乾燥 した後、次の方法で曲げ強度を測定した。  [0088] For each Reference Example 1 to 6, each composition powder shown in Table 1 was kneaded in a pot mill for 1 hour, and water, a retarder, and water glass having a water content shown in Table 1 were added thereto. After sufficiently kneading with a spatula, this was filled into an acrylic mold to obtain a molded body (sample) having a height of 10 mm, a width of 10 mm, and a length of 70 mm. Furthermore, this molded body was cured at room temperature for 1 week in a sealed container, dried indoors, and then the bending strength was measured by the following method.
[0089] 曲げ強度については、オリエンテック製の UCT—5Tを用い、スパン 30mmに配置 された 2支点上に、実施例 1〜： L 1のサンプルを置き、支点間の中央の 1点にクロスへ ッド速度 0. 5mmZminの荷重をカ卩えて 3点曲げを行い、サンプルが破壊されるまで の最大荷重を測定し、次の式 1を用いて求めた。  [0089] For bending strength, use the Orientec UCT-5T, place the sample of Example 1 to L 1 on 2 fulcrums arranged in a span of 30 mm, and cross it at the central point between the fulcrums. The load at a head speed of 0.5 mmZmin was added, three-point bending was performed, and the maximum load until the sample was broken was measured.
[0090] [数 1]  [0090] [Equation 1]
曲げ強度 = 3 W L / 2 b d 2 Bending strength = 3 WL / 2 bd 2
[0091] (式中、 W:最大荷重 (N)、 L :下部支点間距離 (mm)、 b :サンプルの幅 (mm)、 d:サ ンプルの厚さ（mm)を示す） [0091] (W: Maximum load (N), L: Distance between lower fulcrum (mm), b: Sample width (mm), d: Sample thickness (mm))
曲げ強度測定結果もあわせて表 1に示した。コンクリートの曲げ強度は 2〜3Mpaで あることから、表 1の結果のとおり、これらの組成物は、常温で適切な強度を発現する 組成物であることが分かる。また、酸ィ匕マグネシウムは単独でも水和〜炭酸ィ匕により 堅固に固化し、これに無機硫酸化合物、無機炭酸化合物、無機リン酸ィ匕合物又は水 ガラス等を混合することで強度を向上させることができた。なお、これらの組成物は、 酸化マグネシウムと、無機硫酸化合物、無機炭酸化合物、無機リン酸化合物又は水 ガラスとの混合物の配合割合により強度が変化し、後述する実施例 1〜21に示すよう に被成形吸着剤の種類、必要とする pH等に応じて適宜配合を決定すればょ ヽ。  The bending strength measurement results are also shown in Table 1. Since the bending strength of concrete is 2 to 3 MPa, it can be seen that, as shown in Table 1, these compositions are compositions that exhibit appropriate strength at room temperature. In addition, acid magnesium can be solidified by hydration to carbonic acid alone, and strength can be improved by mixing inorganic sulfuric acid compound, inorganic carbonic acid compound, inorganic phosphoric acid compound, water glass, etc. I was able to. The strength of these compositions varies depending on the blending ratio of the mixture of magnesium oxide and inorganic sulfuric acid compound, inorganic carbonic acid compound, inorganic phosphoric acid compound, or water glass, as shown in Examples 1 to 21 described later. The formulation should be determined appropriately according to the type of adsorbent to be molded and the required pH.

[0113] また、例えば実施例 9で得た成形体の比表面積の測定結果については、 332m2Z gであった。この場合、使用したハイシリカゼォライトの粉体比表面積は 430m2/gで あり、吸着剤含有成形体ではこれを 70質量％含有して 、るため比表面積の低下は なぐハイシリカゼオライトの細孔構造を保ったまま成形が行われて 、ることを確認で きた。  [0113] For example, the measurement result of the specific surface area of the molded body obtained in Example 9 was 332 m2Z g. In this case, the high silica zeolite used has a powder specific surface area of 430 m2 / g, and the adsorbent-containing molded product contains 70% by mass, so the specific surface area does not decrease.

[0123] 比較例 1のサンプルは混練時の pHは 10.7であったが、その後 pHが上昇し pHは 12を超え、さらに成形体の多孔質性が失われ、ゼォライトが損傷を受け非晶質化し たと考えられる。一方、この比較例 1に pH緩衝剤として硫酸アルミニウムを配合した 実施例 16においては pHが最高 10.7となり、また、予め Ca型変換が行われた人工 ゼォライト 3を用いた実施例 17においては PHが 10.3以下となり、 PHを目標値であ る 11以下にコントロールすることができ、ゼォライトに損傷を与えることなく成形を行う ことができた。また、実施例 12及び 13の検証試験の結果を比較すると、僅かな水ガ ラスの添カ卩により成形強度が増加することが分かる。さらに、例えば実施例 19の吸着 剤含有成形体の吸水率は 44.5%、実施例 20の吸着剤含有成形体の吸水率は 28 .5%であり、体積標準吸水率としては、それぞれ 49%、 41%と極めて優れた吸水特 性を保有して ヽることが分かる。 [0123] The pH of the sample of Comparative Example 1 at the time of kneading was 10.7, but then the pH increased and the pH exceeded 12, and the porosity of the molded body was lost, and the zeolite was damaged and became amorphous. It is thought that On the other hand, in Example 16, in which aluminum sulfate was added as a pH buffer to Comparative Example 1, the maximum pH was 10.7, and in Example 17 using artificial zeolite 3 that had been Ca-type converted in advance, PH was The pH was 10.3 or less, and the PH could be controlled to 11 or less, which was the target value. Molding was possible without damaging zeolite. Further, comparing the results of the verification tests of Examples 12 and 13, it can be seen that the molding strength is increased by adding a small amount of water glass. Further, for example, the water absorption of the adsorbent-containing molded body of Example 19 is 44.5%, the water absorption of the adsorbent-containing molded body of Example 20 is 28.5%, and the volume standard water absorption is 49%, respectively. It can be seen that it has an extremely high water absorption characteristic of 41%.
[0124] なお、吸水率としては、気孔率の測定方法において測定した W1及び W3と次の式 4を用いて算出した。また、体積標準吸水率は、吸水率 (％)に嵩比重を乗じたものに より算出した。  [0124] The water absorption was calculated using W1 and W3 measured in the porosity measurement method and the following equation 4. The volume standard water absorption was calculated by multiplying the water absorption (%) by the bulk specific gravity.

In this adsorption test, the sample of Example 14 (Φ 3 mm pellet shaped product 50 g) was added to 500 ml of a NH 4 ion concentration 200 ppm solution, stirred with a magnetic stirrer, filtered through filter paper, and the residual NH 4 solution The ion concentration was measured with ICP (Inductively Coupled Plasma). In this case, Fig. 1 shows the results of measurement with different stirring times.
[0127] 図 1に示すように、残留 NH4イオン濃度は、攪拌時間の経過に伴って減少しており 、施例 14のサンプルによって溶液中の NH4イオンが良好に除去されたことが分かる  [0127] As shown in FIG. 1, the residual NH4 ion concentration decreased with the lapse of the stirring time, and it was found that the NH4 ion in the solution was well removed by the sample of Example 14.
[0128] また、実施例 15のサンプル（Φ 3mmペレット状成形体 3g)をフッ素濃度 lOOppm に調整した溶液 100mlに添加し、マグネティックスターラーにて 1時間撹拌した後、 濾紙で濾過し、溶液の残留フッ素濃度を ICPにて測定したところ、残留フッ素濃度は lOppmであった。また、本サンプルを用いて成形後もハイド口タルサイトの結晶性が 低下してな!ヽことを XRD (X線回折装置）により確認した。 [0128] In addition, the sample of Example 15 (Φ 3mm pellet-shaped molded body 3g) was added to 100ml of a solution adjusted to a fluorine concentration of lOOppm, stirred for 1 hour with a magnetic stirrer, filtered through filter paper, and the solution remaining. When the fluorine concentration was measured by ICP, the residual fluorine concentration was lOppm. In addition, it was confirmed by XRD (X-ray diffractometer) that the crystallinity of the talcite in the hide mouth did not decrease after molding with this sample.
[0129] これらの有害イオン除去試験の結果が示すように本発明の成形体は、適切な強度 及び耐水性を備えつつ、優れた有害イオン除去性能を示し、水処理剤として好適で あることが確認できた。このように実施例 12〜21の各吸着剤含有常温固化組成物に よれば、吸着剤の吸着特性を損なうことなく所望の形状やサイズに加工し適度な強 度と耐水性とを付与できることが分力つた。  [0129] As shown by the results of these harmful ion removal tests, the molded article of the present invention has an excellent strength and water resistance, exhibits excellent harmful ion removal performance, and is suitable as a water treatment agent. It could be confirmed. Thus, according to the adsorbent-containing room temperature solidifying compositions of Examples 12 to 21, the adsorbent can be processed into a desired shape and size without impairing the adsorption characteristics of the adsorbent, and can be provided with appropriate strength and water resistance.
