The behavior of lanthanide (samarium, europium and ytterbium) chloride species in NaCl-2CsCl eutectic based melts was studied between 823–1023 K employing cyclic voltammetry, high temperature electronic absorption spectroscopy spectroelectrochemistry. Diffusion coefficients the chloro-species, formal standard red-ox potentials thermodynamics formation LnCl 3 from corresponding dichlorides were determined. A series spectroelectrochemical experiments performed to study cathodic reduction Ln(III) ions under potentiostatic conditions. Sm(III), Eu(III) Yb(III) can be reduced by metallic zirconium this reaction investigated using spectroscopy.
