Abstract

Abstract: As part of an effort to develop aqueous isotope harvesting techniques at radioactive beam facilities, 48 V and a cocktail of primary- and secondary-beam ions created by the fragmentation reaction of a 160 MeV/nucleon 58 Ni beam were stopped in an aqueous target cell. After collection, 48 V was separated from the mixture of beam ions using cation-exchange chromatography. The extraction efficiency from the aqueous solution was (47.0 ± 2.5)%, and the isolated 48 V had a radiochemical purity of 95.8%. This proof-of-concept work shows that aqueous isotope harvesting could provide significant quantities of rare isotopes which are currently unavailable at conventional facilities. Highlights: A selective method was developed to separate the multivalent element vanadium from a complex mixture of elements (Z ~ 1–28). Vanadium-48 was produced via heavy-ion fragmentation of a 58 Ni beam at the National Superconducting Cyclotron Laboratory. The primary- and secondary-beam ions, including 48 V, were stopped in an aqueous target cell and characterized. By way of cation-exchange chromatography, the 48 V recovery was 47.0 ± 2.5%. The radionuclidic purity of the recovered 48 V was 95.8 ± 2.5%.
