Abstract
A method for the determination of As,Hg,Se,Bi and Sn in antimony concentrates by hydride generation atomic fluorescence spectrometry(HG-AFS) was established.The effects of dissolving sample and concomitant ions were studied.The sample can be completely soluble in aqua regia.Trace arsenic,mercury,selenium,bismuth and tin of real samples were determinated without chemical seperation in the medium with different acidities by adding tartaric acid to inhibit the hydrolysis of antimony.The detection limits were 0.22 μg/L,0.002 μg/L,0.18 μg/L,0.11 μg/L and 0.50 μg/L for As,Hg,Se,Bi and Sn,respectively.The recoveries of the 5 elements were from 88% to 112%.
