The removal of radioactive elements Na{sup +}, Cs{sup +}, Sr{sup 2+}, o{sup +2} and Eu{sup 3+} was carried out either by chemical precipitation in situ or by using preformed precipitate of cerium (IV) antimonate. Characterization of the produced materials using X-ray diffraction, thermal and infrared analyses was conducted. Capacity, equilibria measurements, selectivity patterns for Na, Cs, Sr, Co and Eu were determined on these matrices at different conditions. The distribution coefficients of cerium (IV) antimonate for strontium and europium are high, nearly 7 {times} 10{sup 3} and 9 {times} 10{sup 3} at a nitric acid concentration below 0.1 and 0.5 M, respectively. The effect of high concentrations of sodium nitrate, boric acid, sodium citrate and EDTA on the sorption of Eu{sup 3+} has been studied. Cerium (IV) antimonate can be used for the separation and consolidation of radwaste into suitable waste form.
