[Determination of total arsenic in sinters by hydride generation atomic fluorescence spectrometry]

A simple and sensitive method was proposed for the determination of total arsenic in sinters by hydride generation atomic fluorescence spectrometry (HGAFS). The method was based on the oxidation of arsenic compounds with strong acid mixtures in the pressure steel bomb. The linear range for AsV determination was 0-300 micrograms/L. The method was validated by analysis of standard reference material (coal fly ash) with satisfactory results and was successfully applied to the determination of total arsenic in sinters with RSD less than 4%.
