摘要:
研究毒死蜱的表面光化学降解以及9种农药和6种表面活性剂对毒死蜱光解的敏化或猝灭作用。结果指出:毒死蜱在玻片表面的光解半衰期为42.62h,抗蚜威、丙烯菊酯对毒死蜱的光解有显著的加速光解作用,光敏效率分别为51.80%和34.38%;林丹、氟氯菊酯、杀螟松对毒死蜱有显著的延缓光解作用,猝灭效率分别为53.76%、25.16%、10.19%。6种表面活性剂中,2201、0201、JFC对毒死蜱的光解有

Studies on the Effects of Selected Pesticides and Surfactants on Photodegradation of Choropyrifos
()
Abstract:
Effects of 9 kinds of pesticides and 6 kinds of surfactants on photodegradtion of chloropyrifos on glass surface were studied under high pressure mercury lamp Two of the pesticides, namely pirimicarb & allethrin, exhibited the marked photosensitive effects, and the marked photoquench effects were observed for lindane, bifenthrin and fenitrothion, respectively The three of surfactants, which were 2201, 0201and JFC, accelerated intensively the photolysis of chloropyrifos
Key words:  chloropyfos,photodegradation,photosenitizer,photostabilizer
