研究了除草剂丁草胺在氙灯、高压汞灯光照下的光解动态.结果表明,丁草胺在氙灯光照作用下,其光解速率为纯水>河水>塘水>稻田水;丁草胺在氙灯光源下的光解速度比高压汞灯下低;其光解率与浓度(剂量)呈反相关;充N2脱O2使丁草胺的光解速度减缓.
The photolysis dynamics of herbicide butachlor in xenon lamp and high-pressure mercury lamp was studied. The results showed that under photoperiod of xenon lamp, the photodegradation rate of butachlor was pure water> river water> pond water> paddy water. The photolysis rate of butachlor under xenon lamp was lower than that under high pressure mercury lamp. The photodegradation rate And the concentration (dose) was inversely correlated; filling N2 deoxy to slow butachlor photolysis rate.
