Description of the Related Art Conventionally, as a method for removing an unpleasant odor or an unpleasant odor, a method based on physical adsorption using a porous body such as activated carbon or zeolite is known (for example, see Patent Document 1). In addition, zeolite has a cation exchange function, and it is known that odor is removed by a chemical method.
一方、ハイドロタルサイト等の層状複水酸化物を用いた臭いの除去方法も知られている（例えば、特許文献２参照）。ハイドロタルサイト等の層状複水酸化物は、層間に種々のイオンや分子等を挿入できる構造を有しており、陰イオン交換機能を発現させることができる。そのため、当該陰イオン交換機能を利用した化学的方法により、臭いを除去することができる。 On the other hand, an odor removal method using a layered double hydroxide such as hydrotalcite is also known (for example, see Patent Document 2).

また、本発明の脱臭剤に用いる層状複水酸化物の形状は、スラリー状で用いるほか、スラリーをろ過・洗浄・乾燥・粉砕して粉末状にしたものや、粒状にしたもの等を用いることができる。なお、粒状で用いる場合、その粒径は特に限定されるものではないが、本発明の脱臭剤に用いる層状複水酸化物の比表面積が２０ｍ２／ｇ以上のものであることから、従来の層状複水酸化物（比表面積の小さい層状複水酸化物）よりも大きい粒径を用いても高い効果を得ることができる。 The layered double hydroxide used in the deodorant of the present invention may be used in the form of a slurry, or may be a slurry obtained by filtering, washing, drying, or pulverizing the slurry into a powder, a granulated slurry, or the like. Can be. When used in granular form, the particle size is not particularly limited. However, since the specific surface area of the layered double hydroxide used in the deodorant of the present invention is 20 m 2 / g or more, the conventional double hydroxide is used. Even if a particle size larger than that of the layered double hydroxide (layered double hydroxide having a small specific surface area) is used, a high effect can be obtained.

To stop ripening, after the mixing of the acidic solution and the alkaline solution is completed, the pH of the mixed solution may be reduced to a value at which the crystal growth of the layered double hydroxide stops. For example, a layered double hydroxide represented by the general formula Mg 2 + 1 -x Al 3+ x (OH) 2 (A n- ) x / n · mH 2 O, matures when the pH is 9 or less. You can stop it. The layered double hydroxide represented by the general formula Zn 2 + 1 -x Al 3+ x (OH) 2 (A n- ) x / n · mH 2 O stops ripening when the pH is 5 or less. be able to.

Further, an acidic solution and an alkaline solution may be mixed in an appropriate amount in the presence of an aqueous solution containing at least one of a deodorizing metal component, a perhalate ion, and a carbonate ion.
以下に、本発明の脱臭剤に用いる層状複水酸化物の具体的な合成方法を説明する。 Hereinafter, a specific method for synthesizing the layered double hydroxide used for the deodorant of the present invention will be described.
例えば、一般式が、Mg2+ 1-xAl3+ x(OH)2(An-)x/n・mH2O（An-はｎ価の陰イオン、ｍ＞０）である層状複水酸化物を製造する場合には、まず、アルミニウムイオンとマグネシウムイオンを含む酸性溶液を調製する。 For example, a layered structure in which the general formula is Mg 2 + 1 -x Al 3+ x (OH) 2 (A n- ) x / n · mH 2 O (A n- is an n-valent anion, m> 0) When producing a double hydroxide, first, an acidic solution containing aluminum ions and magnesium ions is prepared.
アルミニウムイオンのアルミニウム源としては、水中でアルミニウムイオンを生成するものであれば良く、特定の物質に限定されるものではない。例えば、アルミナ、アルミン酸ソーダ、水酸化アルミニウム、塩化アルミニウム、硝酸アルミニウム、ボーキサイト、ボーキサイトからのアルミナ製造残渣、アルミスラッジ等を用いることができる。また、これらアルミニウム源は、いずれかを単独で用いても、２種類以上を組み合わせて用いても良い。 The aluminum source of the aluminum ion is not limited to a specific substance as long as it generates aluminum ion in water. For example, alumina, sodium aluminate, aluminum hydroxide, aluminum chloride, aluminum nitrate, bauxite, an alumina production residue from bauxite, aluminum sludge, and the like can be used. These aluminum sources may be used alone or in combination of two or more.
また、マグネシウムイオンのマグネシウム源としては、水中でマグネシウムイオンを生成する物であれば良く、特定の物質に限定されるものではない。例えば、ブルーサイト、水酸化マグネシウム、マグネサイト、マグネサイトの焼成物等を用いることができる。これらマグネシウム源は、いずれかを単独で用いても、２種類以上を組み合わせて用いても良い。 Further, the magnesium source of magnesium ions is not limited to a specific substance as long as it generates magnesium ions in water. For example, brucite, magnesium hydroxide, magnesite, a fired product of magnesite, and the like can be used. These magnesium sources may be used alone or in combination of two or more.
なお、前記アルミニウム源としてのアルミニウム化合物、マグネシウム源としてのマグネシウム化合物は、前記酸性溶液にアルミニウムイオン、マグネシウムイオンが存在していれば完全に溶解している必要はない。したがって、酸性溶液中に溶解していないアルミニウム化合物やマグネシウム化合物を含んでいても問題なく層状複水酸化物を製造することができる。 The aluminum compound as the aluminum source and the magnesium compound as the magnesium source need not be completely dissolved as long as aluminum ions and magnesium ions are present in the acidic solution. Therefore, a layered double hydroxide can be produced without any problem even if the acidic solution contains an aluminum compound or a magnesium compound which is not dissolved.
また、Mg2+ 1-xAl3+ x(OH)2(An-)x/n・mH2Oで表わされる高結晶質の層状複水酸化物は、アルミニウムイオンとマグネシウムイオンのモル比が１：３（ｘ＝０．２５）となっていることが知られている。したがって、酸性溶液中のアルミニウムイオンとマグネシウムイオンのモル比は、１：５〜１：２の範囲とするのが好ましい。この範囲とすることによって、アルミニウム源とマグネシウム源を無駄にすることなく、物質収支的に有利に層状複水酸化物を製造することができる。 Further, Mg 2+ 1-x Al 3+ x (OH) 2 (A n-) layered double hydroxides highly crystalline represented by x / n · mH 2 O, the molar ratio of aluminum ions and magnesium ions Is known to be 1: 3 (x = 0.25). Therefore, the molar ratio of aluminum ion to magnesium ion in the acidic solution is preferably in the range of 1: 5 to 1: 2. By setting the content in this range, the layered double hydroxide can be advantageously produced in terms of mass balance without wasting the aluminum source and the magnesium source.
酸性溶液に含まれる酸としては、水溶液を酸性にするものであれば特に限定されないが、例えば、硝酸や塩酸を用いることができる。また、結晶内に過塩素酸イオンを含有する層状複水酸化物を合成したい場合には、過塩素酸や過塩素酸塩を用いても良い。また、結晶内に炭酸イオンを含有する層状複水酸化物を合成したい場合には、炭酸ナトリウムや炭酸カリウム等の水溶性炭酸塩を用いても良い。 The acid contained in the acidic solution is not particularly limited as long as it makes the aqueous solution acidic. For example, nitric acid or hydrochloric acid can be used. When it is desired to synthesize a layered double hydroxide containing perchlorate ions in the crystal, perchloric acid or perchlorate may be used. When it is desired to synthesize a layered double hydroxide containing carbonate ions in the crystal, a water-soluble carbonate such as sodium carbonate or potassium carbonate may be used.
アルカリ性溶液に含まれるアルカリとしては、水溶液をアルカリ性にするものであれば特に限定されないが、例えば、水酸化ナトリウム、水酸化カルシウム等を用いることができる。また、炭酸ナトリウム、炭酸カリウム、炭酸アンモニウム、アンモニア水、ホウ酸ナトリウム、ホウ酸カリウムなどを用いることもできる。これらはいずれかを単独で用いてもよいし、２種以上を組み合わせて用いてもよい。アルカリ性溶液は、ｐＨを８〜１４に調製したものを用いることができ、ｐＨを８〜１１に調製したものを用いるのが好ましい。 The alkali contained in the alkaline solution is not particularly limited as long as it makes the aqueous solution alkaline. For example, sodium hydroxide, calcium hydroxide and the like can be used. Further, sodium carbonate, potassium carbonate, ammonium carbonate, aqueous ammonia, sodium borate, potassium borate, and the like can also be used. These may be used alone or in combination of two or more. As the alkaline solution, those whose pH is adjusted to 8 to 14 can be used, and those whose pH is adjusted to 8 to 11 are preferably used.
この酸性溶液とアルカリ性溶液を所定の割合で混合することにより、層状複水酸化物が生成する。この際、上述したように、層状複水酸化物は、生成後の熟成時間を短くする程、比表面積の大きいものを製造することができる。したがって、当該層状複水酸化物合成工程は、当該酸性溶液とアルカリ性溶液の混合が完了した後、２時間以内、好ましくは１時間以内に熟成を止めるのが良く、更に好ましくは、熟成を行わないのが良い。 By mixing the acidic solution and the alkaline solution at a predetermined ratio, a layered double hydroxide is generated. At this time, as described above, the layered double hydroxide having a larger specific surface area can be produced as the aging time after the formation is shortened. Therefore, in the layered double hydroxide synthesis step, after the mixing of the acidic solution and the alkaline solution is completed, aging is preferably stopped within 2 hours, preferably within 1 hour, and more preferably, aging is not performed. Is good.
熟成を止めるには、酸性溶液とアルカリ性溶液の混合が完了した後、当該混合液のｐＨを層状複水酸化物の結晶成長が止まる値まで下げる方法と、水分を除去する方法がある。 To stop the ripening, there is a method of lowering the pH of the mixed solution to a value at which the crystal growth of the layered double hydroxide stops after the mixing of the acidic solution and the alkaline solution is completed, and a method of removing water.
ｐＨを層状複水酸化物の結晶成長が止まる値まで下げる方法としては、例えば、酸性溶液とアルカリ性溶液を混合した後に直ちに水で希釈する方法により行うことができる。例えば、一般式がMg2+ 1-xAl3+ x(OH)2(An-)x/n・mH2Oで表される層状複水酸化物は、ｐＨが９以下となるように水で希釈すれば良い。 As a method of lowering the pH to a value at which crystal growth of the layered double hydroxide stops, for example, a method of mixing an acidic solution and an alkaline solution and immediately diluting with water. For example, the layered double hydroxide of the general formula expressed by Mg 2+ 1-x Al 3+ x (OH) 2 (A n-) x / n · mH 2 O , as pH becomes 9 or less It may be diluted with water.
水分の除去は、吸引濾過、遠心分離など水分と層状複水酸化物とを分離するための適当な分離方法を用いることができる。 For the removal of water, an appropriate separation method for separating water and the layered double hydroxide, such as suction filtration and centrifugation, can be used.
また、本発明の脱臭剤に用いる層状複水酸化物は、上述したように、既に合成された層状複水酸化物に対して脱臭性金属成分、過ハロゲン酸イオン、炭酸イオンを接触させて調製しても良く、また、層状複水酸化物の合成時に同時に合成しても良い。 Further, as described above, the layered double hydroxide used for the deodorant of the present invention is prepared by bringing a deodorizable metal component, a perhalate ion, and a carbonate ion into contact with the already synthesized layered double hydroxide. Alternatively, they may be synthesized simultaneously with the synthesis of the layered double hydroxide.

検体１、検体２および検体３のすべてにおいて、アンモニアの脱臭効果が認められた。特に、検体２および検体３において、アンモニアの脱臭効果が顕著に認められた。また、層状複水酸化物を活性炭に担持させたもの（検体２）よりも、ゼオライトに担持させたもの（検体３）のほうが、脱臭効果が高いことがわかった。 In all of Sample 1, Sample 2 and Sample 3, the deodorizing effect of ammonia was observed. In particular, in Sample 2 and Sample 3, the deodorizing effect of ammonia was remarkably observed. In addition, it was found that the zeolite-supported sample (sample 3) had a higher deodorizing effect than the layered double hydroxide-supported carbon supported sample (sample 2).
