摘　　要：目的:建立饮水中57种农药的GC/MS确证检验方法。方法:采用液-液萃取(LLE)技术,对水样中57种有机磷类、有机氯类、氨基甲酸酯类、菊酯类农药进行提取、净化、浓缩前处理。采用气相色谱/质谱(GC/MS)联用法进行定性测定。结果:本法回收率为89.1%～112.2%,测定精密度为2.4%～14.5%,SCAN检测模式的检出限为0.3μg/L～4μg/L,SIM检测模式的检出限为0.07μg/L～8μg/L。结论:本法简便、快速、灵敏、定性准确,适合于水样中农药的快速鉴定。Objective：To establish a method for identification of 57 kinds of organophosphorus,organochlorines,carbamates and pyrethroids pesticide multiresidues in drinking water by gas chromatography-mass spectrometry.Methods：The pesticide multiresidues in samples were extracted,purified and concentrated by liquid-liquid extraction（LLE）,and the samples were identified by GC/MS.Results：The spiked recoveries and precision（RSD%） were 89.1%～112.2% and 2.4%～14.5%,respectively.The detection limit for Scan and SIM were 0.3 μg/L～4 μg/L and 0.07 μg/L～8 μg/L,respectively.Conclusion：The method is simple,rapid,sensitive,reliable and suitable for the identification of pesticide residues in drinking water.
