摘要：

An addition of sodium hypochlorite solution effectively eliminated the interference by sulfide in the cold vapor atomic absorption spectrometric determination of mercury using tin(II) reduction in alkaline medium. Mercury ranging from 0.01 to 0.5 mu g could be determined within +/-10% error in 100 mt of sample solution containing 10 mg of sulfide by the addition of 1 mL of 10.4%(w/v) sodium hypochlorite solution. The proposed method is rapid (5 min per determination) and has good reproducibility (3.0%).
