N2 - The redox reactions and coordination circumstances of uranium trivalent ions in molten LiCl-CsCl mixtures were investigated by cyclic voltammetry and spectrophotometry. The formal redox potential, E°′(U3+|U), in LiCl-CsCl mixtures with the CsCl mole fraction of 0.2 was more positive than that in LiCl melt. The CsCl system showed the most negative E°′(U 3+|U). The electronic absorption spectra of U3+ in LiCl-CsCl mixtures showed that the intensities of absorption peaks decreased with the increase of CsCl mole fraction. The oscillator strength of the hypersensitive f-f transition, f, decreased with the increase of CsCl mole fraction.
