Abstract
Proton irradiation of a thorium (Th) target can produce Actinium-225 (Ac-225), but the irradiated thorium fissions results in the production of 100’s of other isotopes. SynPhase Lanterns containing sulfonic acid groups were evaluated for the purification of Ac-225 from Th and other fission metals. The SynPhase Lanterns were able to quantitatively and selectively capture Ac-225 and lanthanum (La) over Th. A second purification step would be needed to purify Ac-225 from trace amounts of Th and other fission products. The results from these studies were compared to similar studies performed with cation exchange resins, and the resins were superior at removing impurities.
