食品容器、包装材料用聚氯乙烯树脂及成型品中残留1,1-二氯乙烷的测定方法研究

Study on the Method for Determination of Dichloroethane in Food Container and Food Packaging Products Made of PVC Colophony

探讨了食品容器、包装材料用聚氯乙烯树脂及成型品中残留1,1-二氯乙烷的气相色谱顶空进样的分析方法。该方法具有良好的线性相关性,相关系数为0.9988,回收率达到98.3%—100.8%,RSD小于5%(n=5)。该方法操作简便,可靠,灵敏度高,重复性好。

The dichloroethane in food container and food packaging products made of PVC colophony was determined by GC-headspace. The linear relationship is very good with the recoveries of 98. 3%--100. 8% and the RSD less than 5% （n=5）. The method is simple,credible and accurate in the analyses of dichloroethane in food container and food packaging products made of PVC colophony.
