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

Production of 64Cu via the proton irradiation of 64Ni, 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, b...

Description
Summary:Production of 64Cu via the proton irradiation of 64Ni, 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 64Ni from bath solutions. •Fast, simple, and efficient method to recover Ni-64 from electrolytic solutions.•Versatile method that can be adapted to recover a large variety of metallic species.•Suitable to process solution targets used for the production of radiometals.
