Abstract: The determination of mercury in the presence of Cu, Pb, Ag, Au, Pt, Pd, Se and As by cold vapor atomic absorption spectrometry was studied. Sodium tetrahydroborate(III) was used as a reducing agent. All the elements examined except arsenic exhibited strong interferences. A solution of 1,10-phenanthroline and thiosemicarbazide in 1.5% HCl solution was used as a masking agent. A highly effective reduction of interference by Cu, Ag, Au, Pt, Pd and Se was achieved. The results obtained were applied to the determination of mercury in a copper concentrate.
