Band displacement process with redox reactions for uranium isotope separation by chemical exchange between U(IV) resin and U(VI) solution
Description
The extreme limits for 235U/238U% at ambiant temperature were determined experimentally with a long time band displacement process (almost 1 year) using the isotope exchange reaction between U(IV) resin and U(VI) solution. These limits are 0.738 and 0.712, assuming 235U/238U = 0.725% for natural uranium. The redox reactions, allowing the band displacement, were: (1) in front of the band the reduction of U(VI) in solution by a cationic resin in Ti(III)form; (2) in the tail of the band the oxidation of U(IV) in the resin by a solution containing Fe(III) ions.
