    Abstract

    The method studied at the BELCHIM-CEN Laboratories at Mol is based on partial deacidification of the highly acid effluent and the complete separation of the Sr90 and Cs137 isotopes by selective adsorption on mineral ion exchangers. After storage and simple chemical treatment, the mother liquor may then be discharged. Preparation methods, structure and exchange properties in different media were studied in respect of two mineral ion exchangers are given. The decontamination factors obtained with synthetic solutions (Purex) were at least 106 in respect of Cs137 and Sr90.
    By selecting appropriate elution conditions it was possible to recover in 5 vol. of eluent beds, 99.9% of Cs137, adsorbed on zirconium phosphate.
