Summary Amorphous and anatase-type hydrous titanium dioxides showed typical amphoteric ion-exchange properties. The ion-exchange selectivity for bivalent transition metal ions was studied as a function of both pH and metal ion concentration in ammonium nitrate media. The selectivity series was Co〈Ni〈Mn〈Zn〈Cd〈Cu for the amorphous and Ni〈Co〈Mn〈Zn〈Cd〈Cu for the anatase-type material. The separation factor on the anatase-type material is larger than on the amorphous material. Effective group separation of Co−Ni and Zn−Cd−Cu could be achieved on an ion-exchange column containing the anatase-type hydrous titanium dioxide.
