| Abstract: | In combination with the actual water environmental monitoring and evaluation, the method of determining selenium in water （SL327.3 -2005 and GB/T5750. 6 -2006） is studied. Through the experiments, the optimum conditions of selenium determination by potassium hydride atomic fluorescence spectrometry are analyzed. The instrument parameters and conditions are optimized. The detection limit of the method is 0. 0002mg/L, and the recovery is 97.1% -105%. The accuracy, precision and representativeness of the data, as well as the reliability of the detection method are guaranteed. |
