Conclusions

  1. 1.

    The γ-radiolysis of carbonate solutions of neptunium(VI) saturated with nitrous oxide or containing persulfate ions leads to the formation of neptunium(VII) only at pH > 12. The yield of Np(VII) in a solution of 0.05–0.5 M Na2CO[3 + 0.1 M NaOH is 4.75 ± 0.1 ion/100 eV.

  2. 2.

    The kinetics of the reactions of the CO3 − ion radical with Np (V) and Np (VI) in carbonate-alkali solutions have been studied by pulse radiolysis. The rate constants are equal to (4.4 ± 0.5) · 107 and (9.0 ± 1.5) · 105 liters/(mole · sec) respectively.
