Abstract
Scandium-47 (47Sc) can be used in nuclear medicine as a therapeutic-diagnostic, or “theragnostic,” radioactive medical isotope for cancer detection and treatment. The 47Sc isotope can be produced through the photonuclear reaction 48Ti(γ,p)47Sc by irradiating enriched 48Ti target material. The enriched target material necessary for production is costly; 48TiO2 costs ~ $1550/g, and targets can be > 50 g ($77,500) to produce medically relevant amounts of 47Sc. In order to keep costs low, a highly efficient separation of scandium from bulk titanium is desired, along with efficient methods for recycling the target material. This research is focused on evaluating efficient methods for the separation of scandium from bulk quantities of titanium using commercially available diglycolamide-based and hydroxamate-based extraction chromatography resins (DGA resin and ZR resin, respectively). The sorption of 47Sc and Ti on these resins were investigated at varying concentrations of HNO3, HCl, H2SO4, and HF to explore how they might be used in a large-scale production/processing setting.
