N2 - Performance of hydrous ZrO 2, ThO 2 and magnetite in a column upto 90°C has been evaluated with reference to the sorption of Cr 3+, Mn 2+, Fe 3+ and Co 2+ on them. The general trend in sorption was found to be Cr 3+>Fe 3+>Mn 2+>Co 2+. The sorption of individual ions on these oxides from a mixture of the four ions was also studied at 90°C, by varying different parameters like the amount of sorbent, concentration of the ions, flow rates and pH of the medium. The results indicate that the rate of sorption is rather low. All the oxides showed good sorption in alkaline media. Hydrous ZrO 2 exhibits, in general, better sorption characteristic as compared to hydrous ThO 2 and magnetite.
