Abstract

We report a novel, precipitation-based method for the isolation of Mn from Cr targets for cyclotron production of 52gMn. The separation produces no-carrier-added 52gMn with a decay corrected radiochemical yield of 85 ± 3% and apparent molar activity for DOTA of 1.3 GBq/μmol. This method reduces stable metallic impurities in the purified 52gMn compared to previously reported chromatographic methods.
