| 摘 要： | 以500W氙灯为光源,研究了毒死蜱在2种不同土壤中的光化学降解以及土壤湿度、TiO2、Fe3+对其光解的影响.结果表明,毒死蜱在土壤中光解较快,其半衰期为19.56～25.89 h;TiO2、Fe3+对其光解有显著的促进作用,光解半衰期分别缩短了14.98%和26.29%;土壤水分对于毒死蜱光解的影响与土壤质地有关.

| Abstract: | The photodegradation of chlorpyrifos in two kinds of soils were studied under the irradiation of Xenon Lamp. The results showed that TiO 2,Fe 3+ accelerated the photolytic rates of chlorpyrifos in humid soil. Half lives of chlorpyrifos in humid soil,TiO 2,Fe 3+ were 23 70 h,20 15 h and 17 47 h,respectively. Soil properties were observed playing an important role in decreasing the photolytic rates of chlorpyrifos. |
