气质联用法测定烟用包装膜中的己二酸酯

Determination of adipate plasticizers in cigarette packing film by gas chromatography-mass spectrometry

建立了乙酸乙酯超声萃取、气相色谱-质谱联用法同时测定烟用包装膜中的5种己二酸酯类增塑剂的方法。结果表明,己二酸酯类化合物在0.1～5.0μg·mL-1浓度范围内线性关系良好,5种己二酸酯类的检测限为0.0053～0.0222mg.kg-1,RSD(10%,回收率在76.86%～112.23%之间。该方法能够快速、准确地测定烟用包装膜中的5种己二酸酯类增塑剂。

A gas chromatography-mass spectrometric method was developed for the simultaneous detemination of five kinds adipate plasticizers in Cigarette packing film, Samples were extracted with Ethyl acetate by ultrasonic. The calibration curves of all the target compounds were linear in the range of 0. 1-5.0μg· mL-1. The detection limits were 0. 0053 -0. 0222mg · kg-I ,The relative stan- dand deviation was below 10% ,and The the average recoveries were in the range of 76. 86% - 112. 23%. The method was rapid, accurate,and was suitable for the determination of five kinds of adipate plasticizers in Cigarette packing film.
