Study of ion-exchange properties of hydrated titanium dioxide towards cesium and strontium cations

Study of ion-exchange properties of hydrated titanium dioxide towards cesium and strontium cations Acid-base and sorption properties of spherically granulated material based on hydrated titanium dioxide were studied.

Abstract

Acid-base and sorption properties of spherically granulated material based on hydrated titanium dioxide were studied. It was shown that the sorption capacity of the ion exchanger is due both to the structure (cross-linking density of gels and, consequently, their porosity) and to the number of active acid centers. The kinetic specific features of the sorption of cations were considered and it was found that the sorption kinetics is limited by the intraparticle diffusion. It was shown that the sorbent can be used to purify low-salt technological solutions of liquid radioactive wastes.
