  • Solid-liquid phase equilibria of Np(VI) under 80%, 0.99% and 0.03% C0 2 and of U(VI) under 100% and 0.03% C0 2 were investigated in 0.1 M NaC104 solution of pH ranging 2.9—4.9 at 25±0.1°C. Neptunium was oxidized and stabilized in hexavalent state in the presence of ozone under various C0 2 partial pressures. Aqueous phases of Np(VI) and U(VI) were characterized by pH measurement, liquid scintillation counting, absorption spectroscopy and fluorescence spectroscopy. Solid phases were analyzed by… CONTINUE READING
