摘要
以高压汞灯、氙灯为光源 ,研究腐殖质对乙草胺在水中的光解动态。结果表明 :在高压汞灯或氙灯光照下 ,胡敏酸与富啡酸对乙草胺在水中的光解表现出显著的光猝灭降解作用效应 ,而且这种光猝灭作用效率与胡敏酸或富啡酸的剂量成正相关 。
The effects of Humic acid and Fulic acid on the photolysis of acetochlor in aqueous solution under the irradiation of high pressure lamp and Xenon lamp were studied.The results showed that both humic acid and fulic acid decreased photolysis rates of acetochlor, and displayed a strong photo quenching effect,the photo quenching effects of HA or FA on the acetochlor were significantly and positively related to the dosages of HA or FA,and there was a combined photo quenching effect between the HA and FA.
