建立了人参、黄芪中有机氯农药残留量的气相色谱分析方法,对六六六和滴滴涕各四种异构体、五氯硝基苯的残留进行了测定.样品以正己烷提取,提取液以浓硫酸磺化后直接进行测定.选用BPX-608毛细管柱,GC-ECD检测了9种农药的残留量.方法的最小检出量为5×10-13~1.0×10-12g;加样平均回收率为92.92％~99.13％;RSD为0.70％~4.77％ A gas chromatographic method for the determination of organochlorine pesticide residues in Radix et Rhizoma Ginseng and Radix Astragali was established and the residues of BHC and DDT four isomers and pentachloronitrobenzene were determined.The samples were extracted with n-hexane, Sulfonated concentrated sulfuric acid directly after the determination by BPX-608 capillary column, GC-ECD detection of pesticide residues of 9 kinds of methods the minimum detection capacity of 5 × 10-13 ~ 1.0 × 10-12g; The recoveries ranged from 92.92% to 99.13%, RSD from 0.70% to 4.77%
