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。
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 90.9 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.
