| Research Abstract |
In order to investigate the probability of Ce separation from La, alloy samples were prepared by potentiostatic electrolysis at 0.55-60 V (vs. Li^+/Li) for 1 h in a molten LiCl-KCl-CeCl_3-LaCl_3 system at 723 K. From the results of ICP-AES analysis, the mass ratio of Ce/La in the alloy samples were found to be 84 at 0.51-53 V. Secondly, in order to separate Dy from Nd, an alloy sample was prepared by potentiostatic electrolysis at 0.55-85 V for 1 h in a molten LiCl-KCl-DyCl_3-NdCl_3 system at 723 K. From the result of ICP-AES analysis, the mass ratio of Dy/Nd in the alloy sample was found to be 72 at 0.65 V.
