Photocatalytic Activities of Titanium Dioxide Immobilized on Plastic Films

摘要

Photocatalytic degradation under illumination of blue fluorescent lamps was carried out on fast green in aqueous solution using titanium dioxide immobilized on plastics as photocatalyst. Sol-gel technique was used to prepare titanium dioxide photocatalyst. The removal rate of fast green was studied based on the effect number of dip-coatings, solution concentration,' light intensity, solution temperature and pH of fast green solution medium. The removal of fast green was found to follow first order kinetics.
