| Abstract: | A method for the determination of selenium in selenium-enriched yeast by hydride generation atomic fluorescence spectrometry （HG-AFS） has been developed. The effects of the instrumental and chemical parameters on atomic fluorescence signal of selenium were discussed and the optimum conditions were recommended. The effects of digest reagents on digestion of samples and the interference from foreign ions on selenium were briefly discussed. The detection limit for selenium is 0.078 5 μg/L under the optimum condition. The line ranger is 0-100μg/L. The relative standard derivation is less than 0.45%, and the recovery rate is 95.4%-104.3%. |
