Using hydrochloric acid as the sample matrix, ICP - MS was used for the determination of mercury in drinking water. The detection limit of this methd was 0.0038 ng/mL, and 1.0 and 0.050 ng/mL Hg standard solution were detect for 7 times, and the value of RSD （ n = 7 ） was found 0.7% - 1.4%. Sample recovery rate was 92% -110%.
