| 摘要: |
| 通过建立直接进样-高效液相色谱串联质谱（HPLC-MS/MS）测定污水处理厂进出水中的10种全氟化合物的方法，了解污水厂进出水中全氟化合物污染情况。10种目标分析物在10~500 ng/L范围内具有良好的线性关系，方法检出限为2.3~8.3 ng/L，精密度为2.1%~7.1%，加标回收率为60.6%~91.7%。应用该方法测定某市典型污水厂进出水中的全氟化合物，进水中全氟化合物质量浓度为90.9~206 ng/L，主要污染物是PFOA、PFHxS和PFBS；出水中全氟化合物的质量浓度为67.4~158 ng/L，环境排放量为6.7~22.9 g/d，主要污染物是PFOA和PFHxS。结果表明，该方法能很好地适用于复杂基质中10种全氟化合物的检测。 |

| Abstract: |
| A method for analysis of 10 perfluorinated compounds (PFCs) from wastewater treatment plants (WWTPs) was established using liquid chromatography tandem mass spectrometry (LC MS/MS).good linear relationship in the range from 10 to 500 ng/L. The detection limits were 2.3 to 8.3 ng/L and the precision was 2.1% to 7.1%. The recoveries 10 PFCs in wastewater ranged from 60.6% to 91.7%. The results showed that PFOA, PFHxS and PFBS were main pollutants in influents ranging from 909 to 206 ng/L. PFOA and PFHxS had been mainly detected in effluents ranging from 67.4 to 158 ng/L. The daily es of PFCs at six WWTPS were 6.7 to 22.9 g/d. The method was suitable for the detection of PFCs residues in wastewater from WWTPs. |
