摘要
Abstract
An ultra-high performance liquid chromatography-tandem mass spectrometry(UHPLC-MS/MS)method was developed for the simultaneous determination of 27 PFAS(perfluorinated and polyfluoroalkyl substances)in drinking water.The water samples were pretreated by solid phase extraction(SPE).The ionization mode was ESI-and the multi-reaction monitoring mode(MRM)was used for qualitative analysis.Quantitative analysis was performed by external standard method.The 27 PFAS compounds showed good linear response in the linear concentration range of 0.005-0.2 mg/L,and the correlation coefficient R2 was greater than 0.9990.The recoveries were 82.9%-108%,the relative standard deviations were 1.6-8.6%,and the limits of quantification for 27 PFAS compounds were 3.0-5.0 μg/kg.The method can be used for the detection and analysis of PFAS in drinking water with high accuracy and reliability.In order to provide technical support for the market supervision department.关键词
