The oxidation of U(IV) ions in the diluted solvent phase, 30% TBP/U2PuPu2NO + HNOThe overall reaction stoichiometry is the same as for the oxidation of U(IV) by HNOU(NOThe rate equations of both these rate limiting steps have been determined, with that for the U(IV)-Pu(IV) reaction (5) being given by the equation below, whereThe rate of the second slow stage, the Pu(III)-HNOMechanistically, it was shown that the U(IV)-Pu(IV) reaction may proceed
