| 摘 要： | 建立了测定聚偏二氯乙烯(PVDC)薄膜中癸二酸二正丁酯(DBS)和乙酰柠檬酸三丁酯(TBAC)含量的气相色谱检测方法。采用DB-5毛细管色谱柱进行分离,二氯甲烷为提取溶剂。经萃取、浓缩定容后上机测试,外标法定量。结果表明:DBS和TBAC能够很好地分离,出峰快,峰形好。在3个添加水平下,DBS和TBAC的加标回收率分别为95.8%、98.0%、93.4%和94.8%、95.9%、93.1%,相对标准偏差(RSD)分别为1.2%、3.9%、1.7%和1.1%、1.5%、1.5%,相关系数均在0.999以上,检出限为2 mg/kg。该方法简捷高效,准确性高,可用于PVDC薄膜中DBS和TBAC含量的测定。
