摘要
运用ICP-MS研究包装材料聚乙烯,每平方厘米加2mL浸泡液,样取150cm2,加热温度60～100℃,浸泡2h,在水、乙醇、乙酸和正己烷中铅、铬和镉的变化情况,结果表明这三种金属的迁移量随加热温度的升高而增加,且在不同的加工环境下,重金属的迁移量差别很大。
We researched polyethylene plastic which belongs to food packaging material,added 2mL per square centimetre,taked 150cm2,60-100℃,we saw the change of Pb,Gr,Cd when they in water,enthanol,acetate and N-hexane.The result showed that the higher the temperature,the more translocation of the three metal,and the translocation of heavy metal is different in each kind of processing environment.
