摘　　要：本文介绍了６种拟除虫菊酯杀虫剂在蔬菜中的双柱单检测器多残留分析方法。样品用丙酮提取，弗罗里硅土净化，气相色谱电子捕获检测器定量测定。经对黄瓜、番茄、大白菜、青椒进行添加回收率试验，其回收率在８７．６％～１０５．１％之间，变异系数１．２～７．２％。最低检出浓度０．００１～０．１０ｍｇ／ｋｇ。A method is reported for the determination of multiresidue of pyrethroid insecticides in vegetables by GCwith two columns and one detector. The sample was extracted with acetone, cleaned up with Florisil,anddetermined by GC with electron capt ure detector.Recoveries of fenpropathrin,cyhalothrin, permethrin,cypermethrin. fenvalerate and deltamethrin from cucumber,tomato, Chinese cabbage and green pepper were inthe range of 87.6～105.1%.Minimum detectable concentrations were 0.001～0.1mg/kg。
