A simple and efficient method to recover isotopically enriched Ni-64 from electrolytic solutions

摘要

Production of Cu-64 via the proton irradiation of Ni-64, electrodeposited on a suitable backing substrate, remains the most common method to produce this emerging radionuclide. Some unforeseen cases arise when the electrodeposition does not work and the electrolytic solution needs to be reprocessed, but the presence of salt buffers makes it difficult to recover the nickel to prepare a fresh solution. The aim of this work was to develop a simple and efficient method to recover Ni-64 from bath solutions.
