Abstract
The analysis of reported data on the interaction of ozone with alkaline solutions of PuVI leads to the conclusion that the process of ozonation involves reactions O3 + OH– → HO -2 + O2, O3 + + HO -2 + OH– → O -3 + O -2 + H2O and O3 + O -2 → O -3 + O2. The O -3 radical ion oxidizes PuVI, the HO -2 and O -2 anions reduce PuVII and PuVI and react with O -3 . Using persulfate instead of O3 in aerated solution at 80—95 °C results in thermal decomposition of the S2O 2-8 anion into radical ions of SO -4 , oxidizing OH– to the O– ion, which in reaction with O2 forms O -3 . The oxidation of PuVI proceeds via the formation of an activated complex with O -3 . where charge transfer occurs with the simultaneous elimination of two H+ ions. A similar mechanism is operating in reactions of PuVI with BrO–, Fe(CN) 3–6 , AmVI, and AmVII. Upon the γ-radiolysis of alkaline solutions of PuVI saturated with N2O or containing S2O 2–8 , e –aq is converted into O– and then into O -3 ; F2 and XeF2 in alkaline solutions are decomposed with the formation of H2O2, which prevents producing PuVII.
