する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention mainly aims at removing odors from odor components having a functional group at the end of the molecule, such as aldehydes and mercaptans, by using visible light (sunlight, artificial light). This article relates to a deodorizing method that involves oxidative decomposition.
従来、臭気成分を酸化脱臭する方法として、オゾン、過
酸化水素水、次亜塩素酸ソーダ水等の使用が考えられ、
一部実用化されている。Conventionally, methods for oxidizing and deodorizing odor components include the use of ozone, hydrogen peroxide, sodium hypochlorite, etc.
Some of them have been put into practical use.
その他、白金触媒等を使用する燃焼法及び無触媒の燃焼
法も実施されている。In addition, combustion methods using platinum catalysts and combustion methods without catalysts have also been implemented.
上記従来の方法において、過酸化水素水、次亜塩素酸ソ
ーダ水等の使用は後に水処理が必要となる欠点がある。In the above-mentioned conventional methods, the use of hydrogen peroxide solution, sodium hypochlorite solution, etc. has the disadvantage that water treatment is required afterwards.

を常に供給する必要があり、経済的とは言えない。Gas phase treatment is superior in this respect, but equipment that uses ozone is extremely expensive and is toxic to humans. Furthermore, since platinum is expensive, combustion methods using platinum catalysts inevitably increase costs, and non-catalytic combustion methods require constant supply of combustible matter, which is not economical.
本発明は上記事情に鑑みてなされたもので、取扱いの容

な脱臭が行われるものである。In the present invention, visible light is utilized, and an odor component is brought into contact with or passed through a sensitizing substance whose quantum yield of singlet oxygen production has been improved by the visible light excitation. As a result, the odor components are oxidized and decomposed by the doublet oxygen, resulting in effective deodorization.
以下に本発明の一実施例を説明する。 An embodiment of the present invention will be described below.

発させた。Next, the above mixture was coated with an air permeable polypropylene nonwoven fabric (thickness: 6 mm, 12.5 am x 12.5 dl).
), and normal hexane was evaporated by vacuum treatment.
その結果、ローズベンガルは白色ワセリンと共存してポ

ローズベンガルの空間露出状態が形成される。As a result, rose bengal coexists with white petrolatum and remains in the polypropylene nonwoven fabric, and a porous state is formed by the volatile part of n-hexane, resulting in a sensitizer with increased surface area and excellent quantum yield of singlet oxygen production, i.e.
The spatial exposure state of rose bengal is formed.
