摘要: The stereoselective degradation and transformation of the enantiomers herbicide fluazifop-butyl in soil water were studied to investigate environmental behavior chiral stability optical pure product. Its main metabolite fluazifop was also monitored. LC/MS/MS with Chiralpak IC column used separate fluazifop. Validated enantioselective residue analysis methods established recoveries ranging from 77.1 115.4% RSDs 0.85 8.9% for enantiomers. It found dissipation rapid three soils (Beijing, Harbin Anhui soil), half-lives ranged 0.136 2.7 d. Enantioselective degradations two soils. In Beijing soil, R-fluazifop-butyl preferentially degraded leading relative enrichment S-enantiomer, but S-fluazifop-butyl dissipated faster. There no conversion into or vice versa formation rapidly accompanied fast fluazifop-butyl, enantioselectivity S-fluazifop R-fluazifop found. quick, 0.34 2.52 d, there significant effects pH on showed faster alkaline conditions. This study an evidence enantiomerization fluazifop-butyl.
