摘　　要：采用电感耦等离子体原子发射光谱仪(ICP-AES),同时测定了食品接触材料高分子材料中钡、钴、铜、铁、锂、锰和锌的迁移量,并对ICP-AES法测定时分析线的选择和入射功率、泵速、载气压力的影响,以及基体和共存离子的干扰情况等进行了研究。研究表明,此方法简便快速,回收率为85.9%～108%,相对标准偏差为2.92%～6.78%。Migration quantity of Barium, Cobalt, Copper, Iron, Lithium, Manganese, and Zinc was determined by inductively coupled plasma atomic emission spectrometry. The influence of analysis line, incident power, pump speed, and carrier gas pressure of ICP-AES, and matrix ion interference and coexistence were studied. The results showed that the method is simple and rapid; recovery for the elements determined is from 85.9% to 108%; and RSDs are in the range of 2.92%-6. 78%.
