Photodegradation of Chlorantraniliprole in Aqueous Solution
摘要
Abstract
Photodegradation is an important pathway of degradation of chemicals in water environment. This study investigated the photo-chemical degradation of chlorantraniliprole in aqueous solution under irradiation of UV lamp. The photolysis of chlorantraniliprole could be characterized by first-order kinetic equation, and was negatively correlated with its initial concentrations. Its photolysis was slower in alka-line than in neutral and acidic solutions. The degradation rate of chlorantraniliprole in different types of water was in sequence of ultra-pure water>tap water>pond water>lake water>river water. Hydrogen peroxide(H2O2)showed significant stimulating effect on chlorantraniliprole photolysis, enhancing photolysis rates by 3.11~1.08 times, but such stimulating effect decreased with increasing H2O2 to a certain concentra-tion. These results would advance our understanding of environmental fates and safety assessment of chlorantraniliprole in water environ-ment.关键词
