Electrochemistry of praseodymium in LiF-CaF2
Original language description
The electrochemical behaviour of PrF3 was studied in the LiF-CaF2 (79/21 molar ratio) at 1,213 K. Inert (W) and reactive (Ni) electrodes were used. Pr(III) ions are reduced in a single, three electron exchange. The redox potential of the Pr(III)/Pr couple at the inert electrode was observed very close to the decomposition potential of the LiF-CaF2 melt. Experiments using reactive working electrode were done. The results show the potential shift connected to the alloying reactions of Pr and Ni. Deposition of Pr-Ni layer was confirmed by SEM-EDX analysis. Conclusions for the Pr separation possibilities from spent nuclear fuel were done.
