The sorption of radiostrontium on hydrated titanium(IV) oxide was studied in batch equilibration experiments. The strontium uptake capacity was determined. Batch distribution coefficients were measured as function of solution pH as well as strontium and sodium concentration. The effect of electron beam irradiation on strontium sorption was also examined. The results are of significance in connection with the removal of radiostrontium traces from alkaline sodium salt-loaded wastes of reprocessing plant origin.
