A method is developed for the determination of nine organophosphorus pesticide residues in cereals and kidney beans by capillary gas chromatography with flame-photometric detection. In this method, dichloromethane is used for clean-up after liquid-liquid extraction. It is shown that good separations are obtained using a fused-silica capillary column (DB-1701) by the optimized temperature program. In the spiked levels of 0.012-0.43 mg/kg, the recoveries are from 83.7% to 107%, with the relative standard deviation between 3.2% and 13% and limits of detection from 8.2 to 15 microg/kg. The method is rapid, sensitive, and practical.
建立了一种采用毛细管气相色谱-火焰光度检测法测定谷物和芸豆中9种有机磷农药残留量的方法。该方法在液-液萃取后用二氯甲烷进行净化处理。结果表明，使用熔融石英毛细管柱（DB-1701）并通过优化的温度程序可实现良好的分离。在0.012 - 0.43 mg/kg的加标水平下，回收率为83.7%至107%，相对标准偏差为3.2%至13%，检测限为8.2至15 μg/kg。该方法快速、灵敏且实用。
