| 摘 要： | 目的建立分散液液微萃取(dispersiveliquid-liquidmicroextraction,DLLME)结合气相色谱-四极杆/飞行时间质谱法(gas chromatography high resolution quadrupole time of flight mass spectrometry, GC-Q-TOF/MS)同时测定饮料中21种邻苯二甲酸酯(phthalic acid esters, PAEs)的分析方法。方法样品经正丙醇分散,四氯化碳提取,氮气吹干,正己烷复溶。在该优化的色谱及质谱条件下,采用电子轰击离子源,全扫描方式采集数据,根据碎片离子的精确质量数定性定量。结果 21种邻苯二甲酸酯在5.0～1000.0μg/L范围内呈良好线性关系,相关系数r均大于0.9985,平均回收率为70.1%～109.9%,检出限为1.0～5.0μg/L,定量限为3.0～16.0μg/L,相对标准偏差为3.02%～6.68%。结论该方法具有操作简便、高效快速、回收率高、灵敏度高等优点,可用于分析测定饮料中的21种邻苯二甲酸酯。
