A fast, single-step, and efficient partition between n-hexane and acetonitrile on ready-to-use, disposable mini-columns of Kieselghur-type material has been developed for the cleanup of fatty extracts for organophosphate (OP) pesticide residue determination by gas chromatography with flame photometric detection. Nine OP pesticides (diazinon, etrimfos, chlorpyrifos-methyl, pyrimiphos-methyl, chlorpyrifos, bromophos, bromophos-ethyl, malathion, fenitrothion) most commonly used for protection of stored cereals, oil seeds, and legumes were separated from up to 2.0 g lipidic material with recoveries between 80 and 107% at spiking levels ranging for the different compounds from 0.1 to 5.0 ppm.
已开发出一种快速、单步且高效的方法，可在即用型一次性硅胶类材料微型柱上实现正己烷和乙腈之间的分配，用于净化脂肪提取物，以通过带有火焰光度检测的气相色谱法测定有机磷（OP）农药残留。从高达2.0 g的脂质材料中分离出了九种最常用于保护储存谷物、油籽和豆类的OP农药（二嗪农、乙嘧硫磷、甲基毒死蜱、甲基嘧啶磷、毒死蜱、溴磷、乙基溴磷、马拉硫磷、杀螟硫磷），在不同化合物加标水平为0.1至5.0 ppm的情况下，回收率在80%至107%之间。
