建立了食用油中常见的5种邻苯二甲酸酯( PAEs)类塑化剂的检测方法。食用油样品经乙腈提取后进行冷冻脱脂处理、玻璃ProElut PSA 固相萃取柱净化,GC-MS全离子扫描定性、选择离子监测模式(SIM)定量。结果显示：食用油中5种PAEs加标回收率在76.17%~98.81%之间,相对标准偏差在1.01%~7.20%之间。该方法的仪器检出限(信噪比为3)和最低定量限分别在0.3~2.0μg/L 及1.0~20.2μg/kg之间。该方法检测食用油中PAEs类塑化剂具有较高的准确度和灵敏度。

A method for determination of five common phthalate acid esters ( PAEs ) in edible oil was established. The edible oil samples were extracted by acetonitrile and then frozen to defat,and cleaned up with glass ProElut PSA solid phase extraction column. The qualitification and quantification of the five PAEs were performed by GC-MS in full ion scanning and selected ion monitoring ( SIM) mode respec-tively. The results showed that the average recovery rates of standard addition of the five PAEs in edible oil ranged from 76. 17% to 98. 81% with 1. 01% -7. 20% of the relative standard deviations. The in-strumental detection limits (S/N=3)of the method ranged from 0. 3 μg/L to 2. 0 μg/L,and the limits of quantitation were 1. 0-20. 2μg/kg. This method for the determination of the five PAEs in edible oil had high accuracy and sensitivity.
