Abstract: Trace amounts of selenium and arsenic in water were determined by Automatic wet digestion- atomicFluorescence spectrometry. The linear correlations of standard curves were good（r≥0.9995）. The recovery rate was inthe range of 89.0% to 104.2%（n=6），and the relative standard deviation（RSD）of this method was（n=6）between1.3% and 6.4%. The detection limit of selenium and arsenic were 0.048μg/L and 0.051μg/L. This method has theadvantages of simple operation and efficient analysis，and were successfully used for the determination of seleniumand arsenic in quantities of water.
