Description
（産業上の利用分野）
本発明は、アルカリ処理水砕スラグと鉄（）
化合物とを組合わせてなる新規な脱臭性基剤に関
する。
（従来の技術）
鉄（）化合物を主成分とし、これにアスコル
ビン酸など有機酸成分を結合させてなる組成物
（以下鉄（）組成物という）が極めて活性が高
く各種の機能を示すことは先に本発明者らは見出
し、提案した（特開昭59−132937号、同60−
66753号公報）。
特にこの鉄（）組成物は悪臭ガス例えば、ア
ンモニア、含硫黄化合物の吸着、除去作用が優れ
ている。
（発明が解決しようとする問題点）
しかし、上記の鉄（）組成物は従来のものよ
り格段に優れた脱臭機能を示すが、吸着ガスの
pHにより吸着性が影響を受け、酸性ガスの吸着
がアンモニアガスの場合より劣るという難点があ
り、この点の克服、制御の点でまだ満足すべきも
のとはいえなかつた。
また鉄（）組成物単独ではコストが高いの
で、実用上の観点から、適当な担体の開発が要求
されていた。
（問題点を解決するための手段）
本発明者らは、上記の鉄（）組成物の問題点
を克服するため鋭意研究を重ねた結果、本発明者
らが先に提案したアルカリ処理水砕スラグ（特許
第1115603号）に所定比率で混合し、水分を所定
量含有させることにより、コストを低下させると
ともにPH依存性の点に克服しうることを見出し、
この知見に基づき本発明を完成するに至つた。
すなわち本発明は、微粉状水砕スラグを少なく
とも0.5Nのアルカリ溶液にて少なくとも30分間
処理後、該処理水砕スラグをろ別分離、水洗後加
熱乾燥して得たかさ比重が低下され且つ比表面積
が増大された表面特性を改良した水砕スラグ（以
下、単にBSという）に対し、鉄（）組成物を
混合し、かつ含水率10〜50重量％としてなること
を特徴とする脱臭性基剤（以下第１発明という）
及びBSを有機酸で中和した後、この水砕スラグ
を鉄（）化合物を主成分としこれに有機酸成分
を結合させてなる組成物と混合してなることを特
徴とする脱臭性基剤（以下第２発明という）を提
供するものである。
本発明（第１発明及び第２発明をいう）におい
てBSに対する鉄（）組成物の混合比は５〜60
重量％が好ましく、10〜50重量％がより好まし
く、20〜30重量％が特に好ましい。鉄（）組成
物が５重量％未満では鉄（）組成物が反応の主
体であるため、その量が不足であり、60重量％を
越えて多すぎると鉄（）組成物の添加割合に比
しての性能向上は生じないのである。
本発明に用いられるBSは安価な比表面積の大
きな固体塩基であり、前記特許第1115603号記載
の方法により調整できる。このBSは鉄（）組
成物との共存により悪臭としての酸性ガス（硫化
水素、メチルメルカプタン、二硫化メチル、悪臭
有機酸）の吸収性を著しく向上させる。すなわち

本発明に用いられるBSの調製例を示す。
(Industrial Application Field) The present invention relates to alkali-treated granulated slag and iron ()
The present invention relates to a novel deodorizing base formed by combining a compound with a compound. (Prior art) It is known that a composition (hereinafter referred to as an iron() composition) which has an iron() compound as its main component and binds an organic acid component such as ascorbic acid thereto is extremely active and exhibits various functions. The present inventors previously discovered and proposed (Japanese Patent Application Laid-open Nos. 59-132937 and 60-
Publication No. 66753). In particular, this iron composition has excellent adsorption and removal effects on malodorous gases such as ammonia and sulfur-containing compounds. (Problem to be solved by the invention) However, although the above-mentioned iron () composition exhibits a deodorizing function that is much superior to conventional ones, it
Adsorption properties are affected by pH, and adsorption of acidic gases is inferior to that of ammonia gas, which is a disadvantage, and the ability to overcome and control this problem has not yet been satisfactory. Furthermore, since the iron () composition alone is expensive, development of an appropriate carrier has been required from a practical standpoint. (Means for Solving the Problems) As a result of extensive research in order to overcome the problems of the above-mentioned iron () composition, the present inventors have developed the alkali-treated granulated We discovered that by mixing slag (Patent No. 1115603) at a predetermined ratio and containing a predetermined amount of water, it is possible to reduce costs and overcome the PH dependence.
Based on this knowledge, we have completed the present invention. That is, the present invention provides a method for treating finely powdered granulated slag with an alkaline solution of at least 0.5N for at least 30 minutes, separating the treated granulated slag by filtration, washing with water, and heating and drying. A deodorizing group characterized by mixing an iron () composition with granulated slag (hereinafter simply referred to as BS) having improved surface properties and increased surface area, and having a water content of 10 to 50% by weight. agent (hereinafter referred to as the first invention)
and BS are neutralized with an organic acid, and then this granulated slag is mixed with a composition comprising an iron () compound as a main component and an organic acid component bonded thereto. (hereinafter referred to as the second invention). In the present invention (referring to the first invention and the second invention), the mixing ratio of the iron () composition to BS is 5 to 60
% by weight is preferred, 10-50% by weight is more preferred, and 20-30% by weight is particularly preferred. If the iron () composition is less than 5% by weight, the iron () composition is the main body of the reaction, so the amount is insufficient; if it exceeds 60% by weight, the amount is too high compared to the addition ratio of the iron () composition. Therefore, no performance improvement occurs. The BS used in the present invention is an inexpensive solid base with a large specific surface area, and can be prepared by the method described in the above-mentioned Patent No. 1115603. This BS significantly improves the absorption of malodorous acidic gases (hydrogen sulfide, methyl mercaptan, methyl disulfide, and malodorous organic acids) by coexisting with the iron() composition. In other words, alkali-treated granulated water alone has a deodorizing effect, but even a simple mixture of iron () composition and BS exhibits its effect synergistically. Examples of iron () compounds that are the main components of the iron () composition used in the present invention include ferrous sulfate, ferrous chloride, ferrous nitrate, ferrous bromide, and ferrous iodide. In addition to iron () inorganic salts such as iron and ferrous ammonium sulfate (Mohr's salt), there are iron () organic salts such as ferrous gallate, ferrous malate, and ferrous fumarate. The iron() compound is not limited to those exemplified above, and any compound can be used as long as it dissolves in water and forms divalent iron ions. In the present invention, organic acid is used in a broad sense. The organic acid component has the effect of stabilizing the active divalent iron ion by coordinating with the divalent iron ion of the iron() compound. Examples of such organic acids include ascorbic acids, gluconic acids, and carboxylic acids. Ascorbic acids herein refer to ascorbic acid, isoascorbic acid, alkali metal salts thereof, and include all of the D-form, L-form, and DL-form. Particularly preferred is L-ascorbic acid. The carboxylic acids are not particularly limited, but oxyacids such as citric acid, isocitric acid, lactic acid, tartaric acid, malic acid, etc. are used. Also, amino acids such as ethylenediaminetetraacetic acids and 4,5-diaminopyrimidines are preferably used. In this iron() composition, an iron() compound is the main component. The ratio of iron () in the iron () compound to the organic acid component is preferably in the range of 1:0.02 to 0.30 (weight ratio), more preferably 1:0.02 to 0.13 when the organic acid component is ascorbic acid. Particularly preferred is a ratio of 1:0.03 to 0.10. In addition, when the organic acid component is a carboxylic acid such as citric acid, the ratio of iron () to the organic acid component is 1:0.01 ~
A range of 0.80 is preferable. Even if the organic acids are used in amounts exceeding the upper limit of the above range, no increase in effectiveness can be expected and it becomes uneconomical, while below the lower limit, freshness preservation and deodorizing functions become insufficient. In the present invention, the organic acid components may be used alone or in combination of two or more. When used in combination, a combination of ascorbic acid and citric acid is preferred, and since citric acid acts auxiliary to ascorbic acid as a stabilizer, the amount thereof may be small. In addition, sodium chloride in this iron () composition is
It is preferable to contain 0.5 to 15% by weight in order to promote the deodorizing effect. In order for the iron () composition of the present invention to exhibit activity, it is necessary that an organic acid component such as ascorbic acid, gluconic acid, or citric acid be bound to the iron () compound as the main component. Such a composition can be prepared by mixing and dissolving the two components in an aqueous solution and drying and pulverizing the mixture by spray drying, freeze drying, or the like. It is also preferable to add alum to the iron composition to stabilize the deodorizing function. The amount of alum added varies depending on the purpose and form of use of the deodorizing base, but it is used up to 100% by weight based on the total amount of iron () compound and organic acid component, but it is 2 to 20% by weight. A range of % is preferred. The alum is not particularly limited, but potassium alum, ammonia alum, sodium alum, etc. are preferred, with roasted alum being particularly preferred. Although there are no particular limitations on the method for preparing the composition of the present invention, which consists of BS and iron () composition, it is preferable to prepare the composition by mixing powders of both in a predetermined ratio. The specific surface area of BS powder in this case is 50-70
m 2 /g is good. This mixture is molded by conventional methods and used as tablets, tablets, and granules. In the composition of the first invention, the effect is further improved when a small amount of water is retained. Its water content is usually 10% by weight or more, preferably 10-50% by weight
and more preferably 20 to 30% by weight. Since BS has a water supply rate of over 60% of its own weight at saturated vapor pressure, moisture adjustment can be achieved by leaving it in the place where it will be used. In the composition of the second invention, in order to further enhance the absorption of basic gases (ammonia, trimethylamine), etc., it is sufficient to use BS that has been previously neutralized with an organic acid and dried. Such organic acids include monobasic acids such as acetic acid and propionic acid;
Using BS treated with dibasic acids such as maleic acid, malonic acid, succinic acid, and oxalic acid, and other oxypolybasic acids such as malic acid, tartaric acid, and citric acid, after mixing and conditioning with iron () composition. When used in the form of powder or granules, it not only excels in deodorizing basic gases such as ammonia, but also has a high specific surface area (60 to 100 m 2 /g) that forms a modified surface layer that is effective against organic solvents, etc. It also shows affinity for gas components (e.g., styrene, cresol, acetaldehyde, etc.) and is used in a wide range of applications. In this case as well, the mixing ratio of the acid-treated BS and the iron () composition may be the same as above. In this case, water 5
It is preferably contained in an amount of at least 5% by weight, and more preferably has a water content of about 5 to 10%. A composition using such organic acid-treated BS can be prepared, for example, as follows. 1-5%
Add 10g of BS to 50g of organic acid solution, stir for 30 minutes, leave overnight to filter and dry (overnight at 110°C), and add 10 to 50% by weight of iron () composition, preferably 25 to 50% by weight.
An adsorbent with excellent ammonia gas adsorption properties is obtained by supporting 30% by weight. Furthermore, as a method for surface modification of BS, an aqueous solution of an iron () composition was directly added to change the liquid from neutral to acidic, and from this a powder of the composition of the present invention having excellent ammonia odor removal performance was prepared. Good too. (Effects of the Invention) The present invention combines an iron () composition with BS, and exhibits significantly higher adsorption power for acidic malodorous gas components than when each is used alone. On the other hand, since the iron () composition originally exhibits high adsorption performance for ammonia gas, the adsorption performance is less affected by the pH of the malodorous gas, and it has the excellent effect of maintaining high activity over a long period of time. play. Furthermore, in particular, the deodorizing base of the second invention also exhibits adsorption properties for organic solvent-based gases. Furthermore, the composition of the present invention can reduce the content of the iron () composition and increase the adsorption activity, and has an extremely large cost advantage. Such a composition of the present invention can be obtained by molding the mixture into a plate shape (60 to 150 kg/cm 2 ) or by simply compression molding.
Not only can it be molded and used as housing, furniture, and packaging materials that have a deodorizing function, but it can also be mixed into plastic fillers and used as molding materials and films that have similar functions. (Examples) Next, the present invention will be described in more detail based on Examples. The iron-ascorbic acid used in the examples is an agent in which 0.03 mole of L-ascorbic acid is bound to 1 mole of iron in ferrous sulfide. Also
BS was adjusted as follows. [Preparation method] According to the method of sample No. 8 of the following reference example. Bulk specific gravity: 0.584 Specific surface area: 57.1 m 2 /g [Reference Example 1] An example of preparing BS used in the present invention will be shown.

[Example 1] Gas 2.4 adjusted to an initial hydrogen sulfide concentration of 4000 to 5000 ml/ m3 was placed in a Tedra bag, and used as an adsorbent.
BS and (BS) + (iron-ascorbic acid) (hereinafter referred to as
1 g of iron (referred to as composition) powder was pressurized to 100 kg/cm 2 and molded to form a disc with a diameter of 13 mm. This is crushed into approximately 8 fractions, this deodorizing base is packed into a column of a deodorant analyzer, and gas with a constant initial concentration is passed at a rate of 1/min for 60 minutes to cause adsorption. Measure the initial concentration and the gas concentration after 60 min.
times). Next, the gas in the Tedra bag was replaced with the initial concentration, and the same adsorbent was used to adsorb it under the same conditions.The concentration of the treated gas was measured after 60 minutes, and the process was repeated approximately 8 times. is shown in Figure 1. Next, a similar test was conducted using the above deodorizing base containing 23.1% by weight of water. The graph in FIG. 1 is as follows. Graph Iron () composition content (wt%) Moisture content (wt%) A 50 0 B 10 0 C 0 (BS only) 23.1 D 0 23.1 E 10 23.1 F 20 23.1 G 30 23.1 H 40 23.1 I 50 23.1 As is clear from the drawing, in dry conditions, the adsorption amount of hydrogen sulfide is small with BS, a mixture of iron-ascorbic acid and BS, and iron-ascorbic acid alone. ), or by mixing BS and iron-ascorbic acid powder (freeze-dried or spray-dried) and molding, and then allowing the adsorbent to retain moisture, its performance can be significantly improved. Recognize. This is due to the solid base properties of BS.
It is interpreted that hydrogen sulfide dissociates in the basic region and becomes ionic, and that this sulfide ion (S 2- ) becomes a hydrosulfide ion (HS - ), which reacts with iron () compositions and compounds. be done. [Example 2] An H 2 S adsorption test was conducted using compositions in which the addition ratio of iron ()-ascorbic acid to BS was varied. When 200μ of water is added to 1g of desiccant, the content is 16.7%. The results are shown in FIG. From the results shown in FIG. 2, it can be seen that even if the addition ratio of iron ()-ascorbic acid to BS is changed from 20 to 40%, there is no significant difference in adsorption performance between these changes. [Example 3] Addition rate of iron-ascorbic acid to BS: 40
A hydrogen sulfide adsorption test was conducted in the same manner as in Example 1, changing the content from 9.1 to 23.1% by weight. The results are shown in Figure 3. From the results in the same figure, it can be seen that when the water content is around 10%, sufficient adsorption performance is not expressed, but when the water content increases from 15% to 25%, the effect increases. [Example 4] Except for treating BS with a citric acid solution, using a composition in which the acid-treated BS was mixed with iron-ascorbic acid (iron() composition) at a predetermined ratio, and using ammonia gas at a predetermined concentration. An adsorption test was conducted in the same manner as in Example 1. The results are shown in Figure 4. From the results in the same figure, BS treated with 5% citric acid
and iron-ascorbic acid at a weight ratio of 1:1, compared to 100% iron-ascorbic acid.
It can be seen that the adsorption performance is low when the number of adsorptions is small, but when adsorption is repeated, the adsorption performance reverses.
