微波溶样ICP-MS测定海产品中十六种元素

Microwave Acid digestion ICP MS Method for the Determination of Sixteen Elements in Marine Products

本文利用微波消解ＩＣＰ－ＭＳ法测定了海产品种Ｎａ、Ｍｇ、Ａｌ、Ｐ、Ｃｒ、Ｍｎ、Ｆｅ、Ｎｉ、Ｃｕ、Ｚｎ、Ａｓ、Ｓｒ、Ｍｏ、Ｃｄ、Ｐｂ、Ｈｇ，并利用国家标准物质贻贝ＧＢＷ０８５７１验证了方法的准确度，测定值与标准值吻合，同时用多内标法有效地校正了基本干扰。方法简便、快速、准确、可靠。

Microwave acid digestion samples and ICP MS method were established for the determination of Na,Mg,Al,P,Cr,Mn,Fe,Ni,Cu,Zn,As,Sr,Mo,Cd,Pb and Hg in marine product,According standard sample GBW08571 mussel,we cheek the method accuracy and precision.The accuracy average values are 96 7%.These results are very suitable for the reference values.The RSDs of all elements are less than 5%.We use several internal standard correction method to correct the matrix interference.The method is simple,rapid,accurate and reliable.
