Abstract

A method for the determination of trace in stone by hydride generation atomic fluorescence spectrome-try(HG-AFS) has been described. In this method, As was pre - reduced by L - cysteine. the influence of HG-AFS operation conditions, acidic media and concentration of KBH4 solution have been studied. The detection limits of As is 0. 058μg/L respectively. The recoveries of the method were 92.67% - 104. 88% , RSD 0.6% (n = 11). This method is accurate, quick - acquired and convenient. It is used in the determination of trace arsenic in stone with the result is satisfactory.
