摘要
本方法采用顶空GC-MS测定EVA材料中的苯乙酮和2-苯基-2-丙醇的释放量。方法检测限为5 mg/kg,EVA材料中的平均加标回收率为90.0%~105%。方法简捷、快速、准确,适用于EVA材料中苯乙酮和2-苯基-2-丙醇释放量的测定。
An analytical method based on using headspace extraction EVA material,the capillary vessel column gas phase mass spectrography carried on qualitative and quota to acetophenone and 2-Phenyl-2-propanol release.The method examination limit was 5 mg/kg,the mean recoveries for packaging material samples were 90.0 %~105 %.The method was accurate,simple,rapid and feasible for the inspection of acetophenone and 2-Phenyl-2-propanol release in EVA materials.
