Abstract
The paper deals with the retention of U(VI) and U(IV) species out of aqueous solutions, on Eichrom resins: as : DGA, TEVA and UTEVA. Some solutions of UO2 2+ and U4+ in HCl and HNO3 were first prepared, having different concentrations. The retention of uranium species separately or out of mixture solutions on DGA, TEVA and UTEVA resins under various experimental conditions, in static contact between the solution and the solid masses, was followed spectrophotometically. The retention degree on resins of the U(IV) was higher than that of the U(VI) , for all three resins which were investigated, whereas the adsorption of U4+ and UO2 2+ ions on these solid masses decreased in the order below:
