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