Distribution coefficients have been measured for the partition of metal ions. Th(IV). Mg(I1), Ni(II) and Cu(II) between cation exchange resin of Dower HCR-S and water-. water - organic solvent - HCI solutions. The effect of variation in concentration of isopropanol. acetone and dioxane on the distribution coefficients of the metal ions have been studied. The effect of change in the acidity of the medium has also been studied by vaIying (HCl). The possibilities of several useful separations has been suggested and the distribution coefficient data was calculated.
