Objective:A method was studied for the analysis of Hg in Baochisan by using ICP-MS.Method: Hg in Baochisan was analyzed by using ICP-MS.The samples were digested by microwave.Bi was selected as internal standard
and instructment parameters were adjusted to optimum working conditions.The reagent blank
standard series and sample solutions were added to equipment and detected.The accuracy was estimated by precision and recovery.Result: The linear range of Hg was 0.25-25 μg · L-1.The average recovery was 99.62% and RSD 1.12%
And determination result of the Hg in Baochisan was 0.201
0.207
0.203 mg · g-1 respectively.Conclusion: The method is simple and fast with low detection limit and high accuracy
can be used to protect quality control of Baochisan.
