Abstract

The results concerning the reduction of U(VI) adsorbed on anion exchange resin as uranyl chloro complexes and sulfate complexes with V(III) in HCl and H2SO4 solution are presented. The reduction of uranyl sulfate adsorbed on anion exchange resin (UO2SO4(R)) in 0.05 M sulfuric acid was carried out, the reaction rate being first order with respect to both concentrations: [U(VI)(R)] and [V(III)]. From Arrhenius plot the activation parameters of the reaction between U(VI)(R) and V(III) in sulfuric acid solution were determined: E a = 34.9 ± 0.9 kJ/mol; ΔΗ ≠ = 35.5 ± 0.9 kJ/mol and ΔS ≠ = −165.7 ± 3 J/K mol. The reduction reaction rate makes possible the utilization of this reaction for displacement of the uranium adsorption band in a 235U separation column packed with anion exchange resin.
