Abstract

A method was established for the determination of the trace mercury in drinking mineral water.The effect of the sewage sample treated with aqua regia(1+1),acid medium and reducing agent on the determination of the mercury were studied.Under the optimum conditions,the linear range of determination was 0～2.0 ng·mL~(-1),the detection limit was 0.0003 μg·L~(-1).The average recovery was between 95%～104%.The method was accurate,rapid and convenient with satisfactory results.
