    • Abstract


      Sorption properties of hydrous thorium oxide depend very much on the preparatory conditions. The sorption of alkali metal ions from alkaline solutions gives rise to a sequence: Li+>Na+>K+>Cs+>NH4+ and that for transition metal ion: Cu2+>Co2+>Ni3+. A sequence for the sorption capacities for the anions: CrO42−>Cl>NO3Br>CNS has also been established. Results indicate that hydrous thorium oxide is both a weakly acidic and weakly basic amphoteric exchanger.
