摘　　要：采用大体积固相萃取富集地表水中SVOCs和氨基甲酸酯类农药,再以气相色谱-质谱和超高效液相色谱-串联质谱联用对目标物定性定量。通过优化固相萃取条件,使SVOCs在0.500 mg/L^10.0 mg/L之间,氨基甲酸酯类农药在1.00μg/L^100μg/L之间线性良好,方法检出限为0.002μg/L^0.009μg/L,加标回收率分别为70.5%~105%和78.5%~124%。用该方法测定某流域地表水,结果邻苯二甲酸酯类物质、多环芳烃类、酚类、硝基苯环类化合物等SVOCs,以及克百威、仲丁威等氨基甲酸酯类农药检出。A simultaneous extraction and determination method was developed by coupling high capacity solid phase extraction with gas chromatography-mass spectrometry( GC / MS) and ultra performance liquid chromatography-tandem mass spectrometry( UPLC-MS / MS) for semi-volatile organic compounds( SVOCs) and carbamates pesticides in surface water. The average recoveries of SVOCs ranged from 70. 5% to 105% and the detection limits were between 0. 002 μg / L and 0. 009 μg / L. The recoveries of carbamates ranged from 78. 5% to124%. Some SVOCs and carbamate pesticides,such as phthalate,polycyclic aromatic hydrocarbon,phenols,nitrobenzene,carbofuran,bassa and so on were detected in surface water by this method.
