摘要
建立了同时测定人参中五氯硝基苯及四种六六六异构体的方法。人参经丙酮-正已烷(1∶2)提取、浓硫酸纯化后,采用OV-1701弹性玻璃毛细管柱、电子捕获检测器测定上述5种有机氯农药。方法快速、简便、准确。
A method for the detection of residual amount of pentachloro nitro benzene (PCNB ) and benzene hexachloride isomers, in Ginseng was developed. The pesticides in Ginseng was extracted with acetone-n-hexane (1∶ 2 ), purified with H2SO4, separated on ov-1701 flexible glass capillary column and determined by electron capture detector (ECD ).
