紫外光辐照条件下水溶液中氧氟沙星的降解机理
|
摘要
研究了紫外光辐照条件下氧氟沙星(O?oxacin,OFL)在水溶液中的降解产物和机理。研究结果表明,紫外光辐照条件下,OFL降解主要生成了2种产物,其反应机理为羟基化和脱甲基作用。
The degradation products and mechanism of o?oxacin(OFL)in aqueous solution under ultraviolet light conditions were studied.The results show that under UV light,the degradation of OFL mainly produces two kinds of products.The reaction mechanism is hydroxylation and demethylation.
