摘　　要：建立了一种基于超高效液相色谱/串联质谱的方法,实现了对北京3个污水处理厂污水中12种全氟化合物(PFCs)的快速、灵敏地定量分析。结果表明,城市污水处理厂进水和出水中短链的全氟丁酸(PFBA)、全氟戊酸(PFPA)和全氟丁磺酸(PFBS)是主要污染物,其中出水中PFBS的质量浓度高达253 ng/L。污水生物处理后,出水中多数PFCs浓度降低,而少数PFCs由于其前体物的降解,导致浓度升高。污水深度处理中反渗透膜对PFCs有较好的去除效果,优于O3处理。The method of SPE-UPLC-MS/MS was used to determine 12 PFCs in wastewater from three wastewater treatment plants（WWTP） in Beijing,and it was proved to be fast and sensitive to quantitatively analyze the PFCs.Results showed that the short chain PFCs including PFBA,PFPA,and PFBS were commonly present in influent and effluent of wastewater treatment plants,and PFBS concentration was up to 253 ng/L.After the biological treatment,the concentrations of most PFCs in effluent decreased,but few PFCs had higher concentration possible due to the degradation of their precursors.In the advanced treatment process,reverse osmosis membrane had better removal efficiency for PFCs than ozone treatment.
