摘要
本方法采用超声溶剂提取包装材料中的抗氧化剂BHT(2,6-二叔丁基对甲酚),毛细管柱气相质谱法对样品中的BHT进行定性和定量。方法检测限为0.1 mg/kg,包装材料中的平均加标回收率为90.0%～105%。方法简捷、快速、准确,适用于包装材料中BHT的快速检测。[
An analytical method based on using ultrasonic extraction packing material, the capillary vessel column gas phase mass spectrography carried on qualitative and quota to BHT. The method examination limit was 0.1 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 BHT in packaging materials.
