摘要：

采用乙腈同时提取蔬菜中的高效氯氰菊酯和氰戊菊酯,用安捷伦的弗罗里硅土柱(500mg;6mL)进行净化,气相色谱法(ECD检测器)进行测定,高效氯氰菊酯的回收率在70.1%~110%,变异系数在1.35%~5.42%,最低检出限为0.001mg/kg。氰戊菊酯的回收率在84.99%~103.68%,变异系数在5.13%~7.15%,最低检出限为0.001mg/kg。

Abstract: High effect cypermethrin and fenvalerate in vegetables were extracted with acetonitrile simultaneously.Extract was purified with Agilent florisil column (500mg;6ml),and analyzed by gas chromatography (μECD detector).These results showed that recoveries of high effect cypermethrin and fenvalerate were 70.1%~110% and 84.99%~103.68%,coefficients of variation were 1.35%~5.42% and 5.13%~7.15%,and the lowest detection limits were 0.001mg/kg and 0.001mg/kg respectively.
