采用超高效液相色谱-串联质谱法测定地表水中21种氨基甲酸酯和有机磷农药,通过优化试验条件,使方法在0.500μg/L～100μg/L范围内线性良好,方法检出限为0.1μg/L～6.2μg/L.对空白水样做3个质量浓度水平的加标回收试验,5次测定结果的RSD为0.3％～9.5％,回收率为82.0％～113％.将该方法用于测定徐州某地表水样品,3个水样均为未检出.%A method for determination of 21 pesticides in surface water by UPLC-MS-MS was developed. By optimizing the experimental conditions, good linearity was observed in the range of 0. 500 μg/L ～ 100 μg/L and the method detection limit was 0. 1 μg/L ～ 6. 2 μg/L. The RSDs of spiked samples with 5 repeated measurements in three concentration levels were 0. 3％ ～ 9. 5％ and the spiked recoveries were 82. 0％ ～ 113％. The method was applied to detecting three surface water samples in Xuzhou, and the residues of all these pesticides were undetected.
