Photo-catalytic De-chlorination of Chlorinated Methane by Titanium Oxide Sol

Abstract

Abstract: Titanium oxide sol was prepared by using inorganic titanium salt, and was used to photo-oxidize chloroform and chlorinated methane solution. Conductivity of solution was increased
when chlorinated methane degraded under UV radiating. Addition of titanium oxide sol makes the degradation rate of chlorinated methane greater, and the
conductivity will be changed. But when the added amount of the sol to solution is too much, the change rate of conductivity will be reduced for the reduced
photo-oxidation of dichloromethane and trichloromethane. Suitable addition amount of the sol is benefit to photo-catalytic de-chlorination of dichloromethane
and trichloromethane in solution.

Key words: titanium oxide sol, photo-catalysis, chlorinated methane, conductivity, de-chlorination
