| Abstract: | A method for the extraction,purification and GC determination of permethrin,fenvalerate and deltamethrin residues in peanut was studied.The pesticide residues were extracted with acetonitrile,purified by a SFE Florisil-1 g column,concentrated with Nitrogen Evaporators and determinated with GC-ECD gas chromatography.The recoveries of this method ranged from 84.1%~90.8%,and the detection limit was 0.01 mg/kg. |
