为了更准确、简便地检测白菜干中常见的有机磷农药残留，建立了超声波萃取气相色谱法检测白菜干中敌敌畏、甲胺磷、乙酰甲胺磷、甲拌磷、氧乐果、乐果、毒死蜱、甲基对硫磷、杀螟硫磷、甲基异柳磷、对硫磷和水胺硫磷等12种有机磷农药残留的方法．结果表明，12种有机磷农药在0．01-1．00μg／mL范围内具有良好的线性关系，回收率为70．6％-112．1％，变异系数1．6％-15．2％，方法检出限为0．004-0．026mg／kg．实际检测样品时，于白菜干样品中仅检出毒死蜱残留量为0．243mg／kg，变异系数为1．7％，其余11种有机磷农药未检出．该方法定量准确、灵敏度高、操作简便，适用于白菜干中常见的12种有机磷农药残留的检测．

In order to detect familiar organophosphorus insecticides residues more accurately and more conveniently, a detection method was established for the determination of 12 organophosphorus insecti- cides residues i methamidophos, isofenphos-methy n dry cabbages by ultrasonic extraction-gas chromatography, including dichlorvos, acephate, phorate, omethoate, dimethoate, chlorpyrifos, parathion-methyl, fenitrothion, 1, parathion and isocarbophos. The results showed that the 12 organophosphorus insecti- cides concentration range of linearity was 0. 01 - 1.00 μg/mL. The percent recoveries were 70. 6% - 112. 1% , coefficients of variation （CV） were 1.6% - 15.2% , and the detection limits were 0. 004 - 0. 026 mg/kg. Some samples collected from market were determined by this method system. It was found that the residue was 0. 243 mg/kg for chlorpyrifos with 1.7% of CV, and the other 11 organophosphorus insecticides were not found. This method was precise, high sensitivity and more convenient, and met the need of organophosphorus insecticides residues detection.
