Abstract
This study investigated the encapsulation and photocatalysis of chlorophenol compounds in water using porphyrin-(polystyrene-b-2-dimethylaminoethyl acrylate) star polymer. The chloride ions generated during photocatalytic process were identified and quantified. 2, 4, 6-trichlorophenol, pentachlorophenol and 2, 4-dichlorophenol were satisfactorily decomposed in the photo-reactor using porphyrin-(polystyrene-b-2-dimethylaminoethyl acrylate) star polymer, with removal efficiencies of 2454, 498 and 760 mg per gram of porphyrin-(polystyrene-b-2-dimethylaminoethyl acrylate) star polymer. The half-life times reached around 30 minutes, with the exception of that for 2, 4- dichlorophenol. The porphyrin-(polystyrene-b-2-dimethylaminoethyl acrylate) star polymer impregnated porphyrin is a promising photocatalyst for the removal of chlorophenols.
