Abstract
Amine-modified grafted cellulose was obtained and its adsorption behaviour using batch technique towards U(VI) in aqueous solutions was studied. Maximum uptake capacity obtained at 25 °C was 150 mg/g. Selective separation of U(VI) from a mixture containing V(V) was achieved. Calculated thermodynamic parameters indicated exothermic nature of the adsorption process, while calculated kinetic parameters indicated that the interaction followed pseudo-second order kinetic model with relatively fast kinetics. Regeneration was achieved using 0.1 M H

with regeneration efficiency up to 95 % over three cycles.
