Scandium-47 (⁴⁷Sc) production via bremsstrahlung irradiation of natural vanadium targets offers significant advantages for producing high purity ⁴⁷Sc; this work evaluates several rapid dissolution and chemical separation techniques for recovering high purity ⁴⁷Sc from irradiated vanadium. Here, techniques developed are combined into a simple, gram-scale, semi-automated target processing system that enables ⁴⁷Sc recovery from irradiated vanadium targets with chemical yields as high as 93 ± 3% and ⁴⁷Sc/V separation factors of 6 ± 3 ·10¹¹ within 90 min total processing times. Future research into H₂O₂ resistant separation techniques and their applicability for direct process coupling to chelation are recommended.
