    氰氟草酯及其活性代谢物在水溶液中的光化学降解研究

    Photo-degradation of Cyhalofop-butyl and Its Metabolite (ACID) in Various Aqueous Solutions

      摘要
    • 摘要: 以紫外光(254 nm)为光源,研究了氰氟草酯及其活性代谢产物氰氟草酸(ACID)在不同水溶液中的光化学降解。结果表明:氰氟草酯及ACID在pH 5.0的缓冲溶液和pH 6.8的去离子水中易发生光解,丙酮的存在对氰氟草酯及ACID的光解有延缓作用。通过GC-MS和HPLC鉴定了氰氟草酯及ACID光解后的部分产物,从而推测了其可能的光解途径。

       

      Abstract: Under UV light (254 nm), the photogradation of cyhalofop-butyl and its ACID in various aqueous solutions were studied. In pH 5.0 buffer solution and deionized water, the photolytic rate were more rapid than that in acetone aqueous solutions. The photolytic products of cyhalofop-butyl and its acid were determined by GC-MS and HPLC. The possible photolytic pathways of cyhalofop-butyl and its ACID in aqueous solutions were also discussed.
