| Abstract: | The author presented a method for the determination of Fenpropathrin residue in 10 kinds of food by using gas chromatography-mass spectrometry method.The samples were extracted by n-hexane,acetonitrile and ethyl acetate through liquid-liquid partition,purified by HLB cartridge and florisil cartridge,and determined by using gas chromatography-mass spectrometry and external standard method.The recovery rate of this method was 70.0%~110.0%,the relative standard deviation was 3.3%~12.3%,and the detection low limit was 0.01 mg/kg. |
