摘要
建立了针对上光剂中包括全氟己酸(PFHxA)、全氟辛酸(PFOA)、全氟壬酸(PFNA)、全氟癸酸(PFDA)、全氟十一酸(PFuDA)、全氟十二酸(PFDoA)、全氟丁烷磺酸(PFBS)、全氟己烷磺酸(PFHxS)、全氟辛烷磺酸(PFOS)、全氟癸烷磺酸(PFDS)在内的10种全氟化合物(PFCs)的液相色谱-串联质谱法(LC—MS/MS)测定分析方法。采用超声法提取测试目标化合物,提取液用混合型弱阴离子交换固相萃取柱净化,用液相色谱-串联质谱仪测定。结果表明,该方法的检测低限均为50wg/kg,相对标准偏差在10%以内,加标回收率85.5%-106.0%。该方法准确、快速,能满足上光剂中全氟化合物测定要求。
The 10 kinds of perfluorinated compounds(PFCs) in polishes were determined by LC -MS/MS( high -performance liquid chromatography - tandem mass spectrometry) method, including perfluorohexanoate ( PFHxA ), perfluorooctanoate ( PFOA ), perfluorononanoate ( PFNA ), perfluorodecanoate ( PFDA ), perfluoroundecanoate ( PFuDA ), perfluorododecanoate ( PFDoA), perfluorobutanesulfonate ( PFBS ), perfluorohexanesulfonate ( PFHxS ), perfluorooctane sulfonate ( PFOS ) and perfluorodecanesulfonate(PFDS ). Ultrasonic method was used to extract target compounds, and the extract with mixed weak anion exchange solid-phase extraction column purification, determined by LC - MS/MS. The results show that the low detection limit of the method is 50μg/kg,relative standard deviation is within 10% ,the standard recovery rate is 85.5% - 106. 0%. The method is accurate and swift,which can meet the demand of the determination of PFCs in polish.
