A critical evaluation of the redox properties of uranium, neptunium and plutonium ions in acidic aqueous solutions (Technical Report) Abstract: Standard redox potentials, E8s and redox processes of U, Np and Pu ions in acidic aqueous solutions are reviewed and evaluated critically. The E8s of reversible redox processes, MO 2 2 /MO 2 and M 4 /M 3 (M: U, Np or Pu) adopted are those proposed mainly by Riglet et al. on the basis of the precise correction of formal potentials, E8 H s, according to the improved theoretical approach to estimate the activity coef®cient. Electrode processes of the U, Np and Pu ions are discussed in terms of current±potential curves, measured so far by polaro-graphy, voltammetry or ¯ow coulometry. Special attention is paid to the irreversible MO 2
