摘要: 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。

Abstract: The photodegradation dynamics of herbicide butachlor in different water was studied under xenon lamp and high pressure mercury lamp illuminating. The result shows that under xenon lamp illuminating, the photodegradation rate of butachlor was in order of pure water>river water>pond water>paddy water. Butachlor photodegraded slower under xenon lamp than under high pressure mercury lamp, and the speed was negatively correlated to the dosage. Moreover, the photodegradation rate was slowed down by filling nitrogen and de-oxygen.
