Tc(VII)-catalyzed oxidation of U(IV) with nitric acid in solution of TBP in n-dodecane

Autor: G. V. Koltunov, Robin J. Taylor, V. S. Koltunov, K. N. Dvoeglazov, V. I. Marchenko

Publikováno v: Radiochemistry. 49:371-375

Oxidation of U(IV) with nitric acid in 30% solution of TBP in n-dodecane is catalyzed by Tc ions; the rate-determining steps are 3U(IV) + 2Tc(VII) → 3U(VI) + 2Tc(IV) and Tc(IV) + Tc(VII) → Tc(V) + Tc(VI). Oxidation of U(IV) is inhibited by the re

Publikováno v: Radiochemistry. 48:348-351

The rate of Pu(IV) reduction with tert-butylhydrazine in an HNO3 solution is described by the equation-d[Pu(IV)]/dt = k[Pu(IV)]2[(CH3)3CN2H4+]/[H+], where k = 69.4 ⊥ 3.0 l mol−1 min−1 at 50°C. The activation energy is E = 122 ⊥ 4 kJ mol−1.
