| 摘 要： | 目的:建立食品包装材料中残留氯乙烯、1,1-二氯乙烷和1,2-二氯乙烷单体含量的自动顶空毛细管气相色谱分析方法。方法:准确称取样品于顶空瓶中,加入N,N二甲基乙酰胺,加盖密封,放入自动顶空进样器,供气相色谱分析,外标法定量。采用DB-624毛细管柱和火焰离子化检测器测定。结果:在本实验条件下,氯乙烯、1,1-二氯乙烷和1,2-二氯乙烷单体线性关系良好(r分别为0.9950、0.9992和0.9977)。平均回收率为84%～102%,相对标准偏差(RSD)为0.29%～1.72%。结论:该法简便、快速、灵敏、准确,适合食品包装材料中残留氯乙烯、1,1-二氯乙烷和1,2-二氯乙烷单体的测定。
