Electrochemical Methods for Determination of Activity Coefficients of Lanthanides in Molten Salts

摘要

In this paper, we have calculated Raoultian standard reduction potentials (E~0) for 14 elements of interest for the pyroprocessing of spent nuclear fuel. Also discussed here is the sound experimental methodology and challenges associated with the employment of an electrochemical cell to determine the activity of species in molten salt systems. Finally, experimental activity data is presented for LaCl_3 and NdCl_3.
