摘要
针对GB/T 21928-2008食品塑料包装材料中邻苯二甲酸酯的测定中对食品塑料包装材料的前处理方法展开研究。通过改变超声温度、超声波功率两种萃取条件,考察了上述条件的变化对食品塑料包装材料中邻苯二甲酸酯迁移量的影响,为进一步开展食品塑料包装材料中邻苯二甲酸酯的测定提供技术支持。
The processing method of determination phthalate （PAEs） in food plastic packaging materials in GB/T 21928-2008 was investigated.By changing the ultrasonic temperature,ultrasonic power,the influence of these conditions on migration quantity of PAEs of plastic food packaging materials were studied.This work will provide technical support for further determination of PAEs in food plastic packaging materials.
