本文探讨了利用气相色谱仪一次测定蔬菜中十种有机磷残留的有效方法。对蔬菜样品利用乙酸乙酯进行抽提,利用活性炭柱进行柱净化,十种农药在HP—17毛细管柱上6分钟内获得完全分离,回收率从80.6％至122.6％不等,10mg/kg以内的线性良好,变异系数为1.5％～7.9％,符合农药残留检测要求。方法快速、灵敏、准确。 This article explored the use of gas chromatography in the determination of ten organophosphorus residues in vegetables effective method. The samples of vegetables were extracted with ethyl acetate and cleaned up with activated charcoal column. Ten kinds of pesticides were completely separated within 6 minutes on HP-17 capillary column, the recoveries ranged from 80.6% to 122.6%, and within 10mg / kg The linearity was good and the coefficient of variation was 1.5% ~ 7.9%, which met the requirements of pesticide residues detection. Method is fast, sensitive and accurate.
