Abstract
[Objective]A method was developed for gas chromatographic determination of haloxyfop-R-methyl in soybean and soil. [Method]Residues of haloxyfop-R-methyl were extracted with an aqueous solution of methanol.The solution was extracted with benzene.The extracts were cleaned up with acid alumina column and were analyzed by gas chromatography with electron capture detection.[Result]The recovery of this method in soybean caudex,soil and soybean was 74.05%-82.25%,85.92%-102.38% and 93.75%-97.55%,respectively.The limit of detection of haloxyfop-R-methyl was 2×10-3ng.The limit of quantification of soybean plants,soil and soybean was 0.002,0.002 and 0.01 mg/kg,respectively.[Conclusion]The method in this study could meet the requirements of pesticide residue analysis in sensitivity,accuracy and precision.
