Abstract: A method has been developed for the determination of selenium in appples by atomic fluorescence spectrometry.The efects of the instrumental and chemical parameters on atomic fluorescence signal of selenium had been studied and optimum conditions recommended.The effects of digest reagents on digestion of samples and the interference from foreign ions on selenium wre briefly discussed.The detection limit (3 σ) of the method was 0.26 μg/L with RSD (Relative Standard Deviation ) of 2.4%.

Key words: Hydride generation Atomic fluorescence spectrometry Selenium Apple
