A multiresidue method for the analysis of 14 organophosphorus pesticides has been developed for the rapid control of residues in vegetables before processing. The residues were extracted in ethyl acetate; the extracts were dried, purified using an Extrelut 20 column and, after concentration, analysed by gas chromatography with a nitrogen phosphorus detector. Recoveries performed in asparagus, beans, French beans, spinach, peas and zucchini at three fortification levels were over 77% for all pesticides except dementon-S-methyl (70%) and omethoate (52%).
已开发出一种用于分析14种有机磷农药的多残留方法，以在加工前快速检测蔬菜中的残留量。残留量用乙酸乙酯提取；提取物经干燥后，使用Extrelut 20柱进行纯化，浓缩后用配有氮磷检测器的气相色谱仪进行分析。在芦笋、豆类、法国豆、菠菜、豌豆和西葫芦中，除甲基内吸磷-S（70%）和氧化乐果（52%）外，所有农药在三个加标水平下的回收率均超过77%。
