| 摘 要： | 实验以400w高压汞灯（主波长：365nm） 光源，降解水中毒死蜱，不同时间取样，样品的一部分革取，并用GC—ECD检测毒死蜱的残留量，结果表明，毒死蜱在90min内的降解率为94％，反应符合零级反应动力学，半衷期为15．2min。样品的另一部分直接进行液质分析，检测到了系列的中间产物，提出了可能的降解机理。

| Abstract: | The chlorpyrifos in water was irradiated through 400w high-pressure mercury lamp. At different time, The photodegradated samples were taken, extracted and detected with GC-ECD. In our condition, chlorpyrifos disappearance was achieved in 90min with half life of 15.2min and the degradation kinetics followed a zero order reaction. At the same time, the sample after illumination was analyzed by HPLC-MSD, series of intermediate metabolites were detected and possible degradion pathway was proposed. |
