An analytical procedure was developed to simultaneously determine bisphenol S, bisphenol F, bisphenol B, bisphenol A, bisphenol AF, tetrachlorobisphenol A, and tetrabromobisphenol A in reed and Callitrichaceae. Homogenized samples were extracted with acetonitrile and purified using an ENVI™-Carb cartridge followed by an NH2 cartridge. The analytes were separated and quantified by ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The recoveries at three fortified levels in reed and Callitrichaceae were 57-108% and 68-106%, respectively, with relative standard deviations of no more than 15% (n=6). The method limits of quantification and detection for the seven bisphenol analogues were 0.005-0.500μg/kg and 0.002-0.150μg/kg, respectively. This method was used to analyze the seven compounds in ten reed and Callitrichaceae samples collected from Zhejiang, China.
开发了一种分析方法，用于同时测定芦苇和水马齿科植物中的双酚S、双酚F、双酚B、双酚A、双酚AF、四氯双酚A和四溴双酚A。将匀浆后的样品用乙腈萃取，并用ENVI™-Carb柱净化，随后用NH2柱净化。通过超高效液相色谱-串联质谱法（UPLC-MS/MS）对分析物进行分离和定量。芦苇和水马齿科植物在三个加标水平下的回收率分别为57-108%和68-106%，相对标准偏差不超过15%（n=6）。七种双酚类似物的定量限和检测限分别为0.005-0.500μg/kg和0.002-0.150μg/kg。该方法用于分析从中国浙江采集的十个芦苇和水马齿科植物样品中的七种化合物。
