摘要：

The effects of various single and mixed metal chloride, sulfate, and nitrate upon the graphite furnace atomic absorption spectrometric determination of Se in aqueous solutions were studied. The results for some chlorides were compared with those for sulfate and nitrate. Among the metals studied (Pd, Hg, Cd, Ni, Cu, Mg, Ag) the best enhancement in the Se atomic absorption signal was obtained by the mixing pair Hg-Pd chloride.
