| 中文摘要: |
| 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1.00 μg/L～100 μg/L之间线性良好，方法检出限为0.002 μg/L～0.009 μg/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。 |
| 英文摘要: |
| 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% to 124%. 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. |
