Objective To establish a method for the simultaneous determination of 17 inorganic elements in oysters by inductively coupled plasma mass spectrometry (ICP-MS). Methods After microwave digestion, Rh was selected as the internal standard element to correct matrix effect, and ICP-MS was used for analysis. Results The correlation coefficients of the 17 elements were not less than 0.9990. The recoveries were 82.8%?111.0%, and the relative standard deviations (RSDs) were 1.0%?7.1%. Conclusion This method can be used to evaluate the mineral elements and safety of oyster due to its properties of rapid and accurate.
