Abstract The distribution coefficients (DC) for HgCl 4 2− , Hg(SO4) 2 2− , Hg(NO3) 4 2− , Ag+, Ag(SCN) 2 − and Ag(NH3) 2 + between aqueous solutions and Dowex A-1 were measured in varying hydrogen ion concentrations. The DC of Ag+ in the NO 3 − media was very low (4 to 6). The DC for the Ag(SCN) 2 − complex decreased as pH increased. The Ag(NH3) 2 + complex had a constant DC of about 65 from pH 8 and above. The trend observed for three mercury complexes in HCl, H2SO4 and HNO3 was similar; the DC decreased steadily from 0.1M to 6M. The HgCl 4 2− complex had the highest DC (9000) while the Hg(NO3) 4 2− complex had the lowest DC (2000).
