| 摘 要： | 采用超高效液相色谱-串联质谱联用法（UPLC-ESI-MS/MS）,建立了分析土壤中11种全氟化合物（PFCs）的方法.以甲醇作为萃取剂,样品经加速溶剂萃取仪（ASE）萃取,固相萃取净化后,使用UPLC-ESI-MS/MS联用仪分析样品中11种PFCs.在6 min内就可快速稳定地将所选取的11种全氟化合物分离,且最低检测浓度为0.518—3.520 pg.g-1之间,这些化合物在土壤中的平均添加回收率在71.2%—119.2%之间.应用此方法测得宜兴市水稻土样品中所选取的PFCs含量为0.006—0.780 ng.g-1之间.

| Abstract: | A method for the determination of 11 perfluorinated compounds(PFCs) in soil by accelerated solvent extraction(ASE) combined with ultra performance liquid chromatography-tandem mass spectrometry(UPLC-ESI-MS/MS)was developed.An ACQUITY UPLC BEH C18 column was applied to separate the analytes in 6 min.11 PFCs standards were detected using this method with the limit of detection(LODs) between 0.518—3.520 pg · g-1.Soil samples were extracted by ASE using methanol as solvent.The extracts were concentrated with rotary evaporation and followed by SPE purification before analysis with UPLC-ESI-MS/MS.The recoveries in soil samples were determined to be in the range of 71.2%—119.2% under the spiked conditions.Analysis of real soil samples collected in Yixing showed that all of the 11 PFCs were detected at the level of 0.006—0.780 ng · g-1.Overall,the data showed that the method developed in this study is sensitive,accurate and suitable for analyzing trace PFCs in soil. |
