摘　　要：目的:建立布渣叶中9种有机氯农药残留气相色谱分析方法。方法:样品用水浸润过夜,用丙酮、二氯甲烷和正己烷超声提取,提取液使用浓H2SO4磺化净化,采用石英毛细管柱分离样品,GC-ECD测定有机氯农药的残留量。结果:加样回收率范围为78.1%～97.8%,RSD为2.4%～8.8%。结论:所建立的方法快速、简便且成本较低。Objective： To establish a method for determination 9 organochlorine pesticide residue in Microcos paniculata by gas chromatography.Methods： The sample was infiltrated with water and extracted with hexane by ultrasonic.The extract solvent was purified by concentrated sulphuric acid.DB-1701 capillary column was used to separate the sample.GC-ECD was applied to determine the residues of organochlorine pesticide.Results： The percentage recoveries were ranged from 78.1% to 97.8%and RSD were from 2.4%to 8.8%.Conclusion： The method established is quick,simple and low in cost.
