Abstract

This study investigated the degradation of commercially used organophosphorous pesticide malathion in aqueous solution by UV-Irradiation process. The process was optimized by varying different parameters such as operating pH, TiO2 loading, H2O2 concentration and initial pollutant concentration. It was observed that COD removal were 91.6 % for 2 ppm initial concentration of malathion and under optimized condition TiO2 loading 3gm/L, pH 6, and H2O2 concentration of 0.625 ml/50ml solution in 16 hours. This study indicates that degradation by UV-Irradiation process could be used as efficient and environmental friendly technique for the degradation of bio-recalcitrant organic pollutants.
