Production of 61Cu using natural cobalt target and its separation using ascorbic acid and common anion exchange resin

摘要

61Cu was produced by natCo(α, xn) 61Cu reaction. 61Cu production yield was 89.5MBq/μAh (2.42mCi/μAh) at the end of irradiation (EOI). A simple radiochemical separation method using anion exchange resin and ascorbic acid has been employed to separate the product radionuclide from inactive target material and co-produced non-isotopic impurities. The radiochemical separation yield was about 90%. Radiochemical purity of 61Cu was 99% 1h after EOI. Final product was suitable for making complex with N 2S 2 type of ligands.
