Photocatalytic degradation is a promising technology for the degradation of endosulphan and lindane. The presence of acetone in the reaction mixture retards the reaction because of the competition for hydroxyl radicals between pesticide and acetone. The pH 7 was chosen as optimum with degradation efficiency of 95% (endosulphan) and 98% (lindane) which coincides with the zero point charge of the catalyst used (pH 6.5-7.5). Second order reaction kinetics was observed for both endosulphan and lindane (5, 7.5 and 10 ppm). Calculated rate constant values (kobs') for initial endosulphan concentration of 5, 7.5 and 10 ppm were 0.0465, 0.0467 and 0.0934/ppm/min, respectively. While for kinetics performed at 5, 7.5 and 10 ppm initial lindane concentrations rate constant values (kobs') were 0.0264, 0.0626 and 0.05/ppm/min, respectively. © 2011 - Kalpana Corporation.
