Photochemical methods for destroying organic pollutants found in industrial wastewaters and groundwaters are being used successfully in environment treatment systems. This study focuses on acetone photodegradation in aqueous solution by UV irradiation (1 kW medium pressure Hg lamp) in the presence and absence of H{sub 2}O{sub 2}. Intermediates such as acetic and formic acids were detected. The kinetic data were evaluated and the reaction mechanisms were postulated considering the influence of oxygen concentration and pH. The generation of {sm_bullet}OH radicals from the photolysis of H{sub 2}O{sub 2} induces a faster decomposition of acetone (depending on H{sub 2}O{sub 2} concentration) than does direct photolysis.
