ABSTRACT
Objective To establish stable and convenient atomic fluorescence spectrometry to determine selenium concentration.Methods The samples were digested by nitric acid-perchloric acid and the selenium was determined by hydride generation-atomic fluorescence spectrometry with step-flow injection technology in NaBH4 acid and 100 g/L K3Fe(CN)6 system.Results The relative standard deviation of the method was less than 5%,the concentration of detection limits was 0.81 ?g/L and the recovery rate ranged from 93.1% to 102.2%.Conclusion Atomic fluorescence spectrometry was convenient and reliable in determining solenium,the digest method of test tube was better than that of normal electrothermal board.
