Abstract

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.
