| 摘 要： | 建立毛细管柱气相色谱法测定蔬菜中9种有机磷农药残留的分析方法。蔬菜经均质,用乙腈提取,CARB/NH2柱净化,丙酮溶解定容,采用DB–1701毛细管柱和火焰光度检测器测定,一次进行9种有机磷农药残留检测。样品加标回收率在80.2%～102.2%之间,相对标准偏差在2.15%～5.32%之间,检出限在0.004 2～0.027 mg/kg之间。实验结果表明,该方法简便、快速、灵敏、准确,各项技术指标满足蔬菜中9种有机磷农药残留检测要求。

| Abstract: | To establish a method for detection of 9 organophosphorous pesticide residues in vegetables by capillary column gas chromatography.After homogenization of vegetables,organophosphorous pesticides were extracted by aceto-nitrile,cleaned by CARB/NH2,solubilized by acetone and made up to volume,detected by DB-1701 capillary column and flame photometric detector.Nine organophosphorous pesticide residues in vegetables could be detected in the same time.The recovery was 80.2%-102.2% with relative standard deviatio... |
