Radiation Stability of Cerium(IV) Antimonate Ion Exchanger

The ion exchange and selectivity behaviour of cerium(IV) antimonate (CeSb) have been systematically investigated as a function of absorbed dose. Changes in ion-exchange capacity, distribution behaviour and infra-red spectra of the irradiated materials have been followed. The irradiated CeSb has been successfully used for the quantitative separation of cesium which suggests its use in the treatment of active liquid wastes.
