Open publisher page 1 citations

Abstract

This paper proposed a sensitive and simple method for the determination of total selenium in coal samples by hydride generation atomic fluorescence spectrometry (HG AFS). The detection limit was 0.40?μg/L with linear range of 0～400?μg/L for Se. The method has been validated by analysis of standard reference coal fly ash with precision of less than 4.5% RSD( w Se =10 -6 , n =4) and has been successfully used for the determination of total selenium in coal samples from different sampling sites.
