摘要
对采用微波消解ICP－MS测定猪肉中砷、镉、铅、镍、铬、铜、汞、锑和锌9种金属元素的含量进行了研究。结果表明，方法测定的线性范围在0～50 ng／mL，检出限为1．2～22．5 ng／mL，精密度在0．28％～4．39％之间，猪肉样品添加回收率为81．5％～112．6％。该方法操作简便、快速、准确，大大提高了检测时效。
In this paper, we introduced the determination of 9 kinds of metal elements, arsenic, cadmium, lead, nickel, chromium, copper, mercury, antimony and zinc in pork muscle, by microwave digestion and ICP-MS. The linear range of standard curve was from 0 to 50 ng/mL, the detection limit was within the range of 1. 2~22.5 ng/mL, and the precision of the method was 0.28%~4.39%. All the recovery rates in meat were between 81.5% and 112. 6%. The method we used in this paper was simple, rapid and accurate, which may greatly improve the detection time and efficiency.
