摘要
建立了一种测定青菜中有机磷农药敌百虫的方法,样品以二氯甲烷提取,活性炭脱叶绿素,毛细管电泳法检测,最低检出限为2×10-6mol L,敌百虫浓度在5×10-5～2×10-6mol L之间,呈现良好的线性关系,r=0.9914,样品加标回收率为90%～102%。
A method for determination of trichlorfon in vegetables by capillary eletrophoresis was established. Sample was extracted by dichloromethane, and chlorophyll was absorbed by active carbon. Calibration curve was linear over the range from 5×10^(-5) to 2×10^(-6) mol/L, with a detection limit of 2×10^(-6) mol/L for trichlorton. The recovery of sampled ranges from 90%～102%.
