Characterization of actinide resin for separation of (51,52g)Mn from bulk target material.

We report an extraction chromatography-based method via Actinide Resin for the isolation of radio-manganese from both natural chromium and isotopically enriched iron targets for cyclotron production of (52g)Mn and (51)Mn. For the separation of (52g)Mn from n(at)Cr, a decay-corrected radiochemical yield of 83.7 ± 8.4% was achieved. For (51)Mn from (54)Fe, a decay-corrected radiochemical yield of 78 ± 11% was achieved. This automatable method efficiently isolates both radionuclides from accelerator target material.
