摘　　要：本文利用微波消解电感藕合等离子体质谱法 (ICP -MS)测定了海产品中Na、Mg、Al、P、Cr、Mn、Fe、Ni、Ca、Zn、As、Sr、Mo、Cd、Pb、Hg,并利用国家标准物质贻贝GBW0 85 71验证了方法的准确度、准确度在 85 %～ 115 % ,平均值为 96 .7% ,测定值与标准值吻合 ,相对标准偏差均小于 5 % ,并用多内标法有效地校正了基体干扰 ,方法简便、快速、准确。Microwave Acid-digestion samples and a ICP-MS method is established for the detection of Na?Mg?Al?P?Cr?Mn?Fe?Ni?Cu?Zn?As?Sr?Mo?Cd?Pb and Hg in Marine product. For example: GBW08571 mussel. According this sample, We cheek the methods accuracy and precision. The accuracy average value is 96.75. These results are very suitable for the reference values. All of the elements RSD is less than 5%. And we use several internal stand correction matrix interference. Rapid? accurate and reliable are the features of the method.
