超高效液相色谱-三重四极杆串联质谱仪测定植物样品中PFOS・ PFOA

         

摘要

[目的]研究运用超高效液相色谱-三重四极杆串联质谱仪测定植物样品中全氟辛烷磺酸(PFOS)和全氟辛酸(PFOA)的可行性。[方法]建立了一种SPE 净化,超高效液相色谱-三重四极杆串联质谱仪 UPLC/MS/MS方法测定植物(绿萝)根、茎和叶中 PFOS和PFOA残留量,并优化了质谱条件和前处理方式,保留时间分别为2.26和2.17 min。[结果]采用碳酸钠(Na2CO3)、四丁基硫酸氢铵(TBAHS)、甲基叔丁基醚(MTBE)作为提取试剂,HLB小柱净化后PFOS在绿萝根、茎、叶中的加标回收率为46.53%~77.35%,变异系数为5.63%~18.52%;PFOA在绿萝根、茎、叶中的加标回收率为59.01%~100.46%,变异系数为2.85%~30.06%,检出限分别为26.90×10-4和3.09×10-4 ng,相关系数均大于0.998。[结论]超高效液相色谱-三重四极杆串联质谱仪测定植物样品中 PFOS 和PFOA满足化合物残留分析要求。%Objective] The study aimed to researched the residue analysis method of PFOS and PFOA using HPLC-MS/MS in plant samples. [ Method] PFOS and PFOA residue analysis method by SPE -ultra performance liquid chromatography tandem mass spectrometry ( UPLC/MS/MS) of in Epipremnum aureum was established.Analysis and determination conditions were optimized, the retention time of PFOS and PFOA is 2.26, 2.17 min.[Result] The experimental results showed that recoveries of PFOS and PFOA were in the range of 46.53%-77.35% and 59.01%-100.46% respectively.The coefficients of variation were 5.63%-18.52% and 2.85%-30.06% respectively.Minimum detect-able mass fraction of PFOS and PFOA were 26.90 ×10 -4 ng and 3.09 ×10 -4 ng,correlation coefficient is greater than 0.998.[Conclusion] Results showed that the developed method can be applied to analyze PFOS and PFOA in Epipremnum aureum.
