| Abstract: | A non-dispersive atomic fluorescence spectrometry combined with sodium borohydride reduction for the determination of mercury has been developed.Under the optimum conditions,there is a linear relationship between the fluorescence intensity and mercury concentration in the range of 0—25μg/L with correlation coefficient 0.9992.The detection limit is 0.02μg/L.The proposed method has been applied to the determination of mercury in battery with satisfactory results.The recovery is 91.6%—103.1%,and the relative standard deviation is less than 4.2%. |
