| 摘 要： | 建立了仿真饰品中6种磷酸酯类增塑剂含量的气相色谱―质谱测定法。对提取方法、色谱条件及质谱参数进行了研究。结果表明,采用正己烷/丙酮(体积比1∶1)微波萃取样品35 min可获得良好的提取效果。所建立的微波萃取―气相色谱―质谱法的定量限为1～2.5 mg/kg,在1～2个数量级浓度范围内,线性相关系数R2在0.999以上,在三个添加水平下回收率在86.63%～98.13%之间。对市售9种塑料仿真饰品的测定结果表明磷酸酯的存在风险极低。

| Abstract: | A method was developed for the determination of 6 phosphate plasticizers in imitation jewelry by gas chromatography-mass spectrometry(GC-MS).Extraction,chromatography and mass conditions were studied.Results showed that the extraction of target compounds can reach a good performance with hexane-ketone(1∶1) under microwave assisted extraction for 35 min.The limit of quantification(LOQ) of the method was 1～2.5 mg/kg.The calibration curves were linear within the concentration of 1～2 order of magnitude with typical correlation coefficients above 0.999.The recoveries ranged from 86.63%～98.13% with three addition levels.Risk of the presence of phosphate plasticizers in imitation jewelry was very low according to the results from 9 commercial samples. |
