The results from some of our recent investigations of actinide redox reactions in nitric acid and tributyl phosphate phases are reviewed, including the oxidation of U(IV) by HNO3 and HNO2 and by Np(VI) and Np(V) in 30 % TBP and by Np(VI) in HNO3. The unusual interactions between U(IV), Tc(VII) and NH3OH+ in HNO3 are also discussed. Finally, the photocatalytic heterogeneous reduction of U(VI) by a colloidal semiconductor is presented.
