Redox equilibrium of the UO22+/UO2+ couple in Li2MoO4–Na2MoO4 eutectic melt at 550 °C
Source abstract
Abstract
Abstract The redox equilibrium of UO22+/UO2+ couple was measured in Li2MoO4–Na2MoO4 eutectic melt at 550 °C by cyclic voltammetry and absorption spectrophotometry. The standard redox potential of UO22+/UO2+ couple was approximately evaluated by cyclic voltammetry. Further, the absorption spectrum and equilibrium potential were measured, repeatedly adding UO22+ source material into the melt containing UO2+. From the correlation between the equilibrium potential of the melt and the concentration ratio [UO22+]/[UO2+] spectrophotometrically evaluated, the standard redox potential of UO22+/UO2+ couple was determined to be −0.847 ± 0.010 V vs. O2/O2−.
