本文介绍了9种有机磷杀虫剂:敌敌畏、速灭磷、甲拌磷、二嗪农、乐果、皮蝇磷、甲基对硫磷、马拉松、对硫磷的多残留检测方法。用丙酮∶水=2∶1(v/v)的混合溶剂来提取残留农药,弗罗里硅土氧化铝柱纯化,气相色谱——火焰光度检测器定量测定。经对苹果、面粉、白菜、茶叶、烟草、土壤和水进行添加上述9种农药标准混合物后的回收率试验,其回收率在80-100%。 This article describes the detection of nine residues of organophosphorus insecticides: dichlorvos, instant phosphorous, phorate, diazinon, dimethoate, skin fly phosphorus, methyl parathion, marathon, parathion. Residual pesticides were extracted with a mixed solvent of acetone: water = 2: 1 (v / v) and purified on a Florisil alumina column. Gas chromatography - flame photometric detector was used for quantitative determination. The recoveries of the nine pesticide standard mixtures obtained from apple, flour, cabbage, tea, tobacco, soil and water were 80-100%.
