광촉매와 광증감제를 이용한 유기염소화합물의 광분해에 관한 연구 = Photocatalytic and Photosensitized Degradation of Organic Chlorocompounds

다국어 초록 (Multilingual Abstract)

Phetodegradation of organic chlorocompounds(chloroform, trichloroethylene, chlorobenzene) in aqueous suspension of several semiconductors(TiO₂, ZnO, SnO₂) and in aqueous solutions of inorganic anion(S₂O_(8)^(2-), NO₃^(-), NO₂^(-)) have been studied. Photocatalytic degradation of organic chlorocompounds was increased in the order of SnO₂ < ZnO < TiO₂. which irradiated by 450W medium pressure Hg lamp through pyex filter Unsaturated and aromatic hydrocarbon was degradated more effectively than saturated hydrocarbon. When inorganic anions was added to reaction solution as photosensitizer, photodegradation of organic chlorocompounds was much increased bs- S₂O_(8)^(2-), but little affected by NO₃^(-) or NO₂^(-), which irradiated by 15W low pressure Hg lamp.
