Abstract: A method for the determiation of Se in selenium-enriched egg by sequential injection hydride generation atom fluorescence spectrometry was established and the interference circumstance of the coexistence ions were discussed at the same time. Under the conditions proposed, detection limit of the Se is 0.082μg/L. Recoveries of standard addition of the Se is proved to be 94.2%~102.9% in samples.
