Abstract  

The sorption of some monovalent, divalent and trivalent metal ions has been studied on a mixed and doped hydrous oxide of iron and zirconium (with iron as a major constituent). The sorption of Sr2+, Cr3+ and Cd2+ was found to be exceptionally high, besides this, the mixed oxide also exhibits significant uptake of Rb+ and Cs+ ions. The effect of doping is quite interesting as the uptake of Fe3+ increases 2-increases 2-fold when the mixed oxide is doped with Sn(II) ion. An enhancement of the same magnitude is also observed in the case of La3+ ions. The amount of maximum uptake was determined and found to be linearly related to the ionic potentials, i.e. charge to radius ratios of the entering cations.
