Abstract

Electronic absorption spectra of tetravalent uranium in LiCl and CsCl were measured. Redox potentials of U⁴ VU^{3 +} and U ³⁺/U⁰ couples were estimated by cyclic voltammetry. By adding SrCl² into the melts, changes in absorption spectra and cyclic voltammograms were seen. The effect of the coexisted Sr^{2 +} on the coordination circumstance of uranium ions was discussed.
