摘　　要：建立了直接进样法和应用PRiME HLB固相萃取柱通过式净化法2种前处理技术,结合超高效液相色谱-串联质谱仪同时测定水中11种氨基甲酸酯类农药的分析方法。样品过0.22μm滤膜直接进样,或者复杂样品经PRiME HLB固相萃取柱通过式净化,超高效液相色谱-串联质谱仪检测,外标法定量。11种氨基甲酸酯类农药均得到有效提取和分离,线性关系良好,相关系数R^(2)≥0.995,方法检出限为0.1~0.3μg/L,定量限为0.4~1.2μg/L,平均回收率为74.4%~83.9%,精密度均小于10%。方法适用于各类水中11种氨基甲酸酯类农药的快速检测。A rapid method was developed for the simultaneous determination of 11 carbamate pesticides in water by direct sampling or PRiME HLB pass-through solid-phase extraction( SPE) coupled with ultra-high performance liquid chromatography-tandem mass spectrometer. The sample was directly injected through a 0. 22 μm filter membrane,or only needed to be purified by a PRiME HLB SPE column,and detected by ultra-high performance liquid chromatography-tandem mass spectrometer,quantifying with the external standard method. The method showed good linear relationships for 11 carbamate pesticides in the detection ranges,with the linear correlation of coefficients( R;)above 0. 995,the limits of detection of 0. 1-0. 3 μg/L,average recoveries of 74. 4%-83. 9% and relative standard deviations( RSDs) less than 10%. The sample preparation method is suitable for rapid detection of 11 carbamate pesticides in water.
