Heating and digestion of water samples by sulfuric acid and potassium permanganate ,low concentration potassium borohydride as the reducing agent ,using AFS-9230 double-channel atomic fluo-rescence spectrometry ,determination of trace mercury in surface water with sequential injection-cold vapor generation-atomic fluorescence spectrometry was carried out. The detection limit is 0.012μg/L ,the rate of recovery is 90%-110% ,RSD<10.0%. The advantages of the method are of high sensitivity ,good preci-sion ,less interference ,simple and convenient operation. At the same time ,the aspect of quality control w as discussed.
