The Performance of two silica based ion exchange resins in the separation of 213Bi from its parent solution of 225Ac

The performance of two inorganic ion exchange resins, Isolute SCX and Isolute SCX-2, were compared to the performance of the organic resin AG-50X8 in the separation of the radionuclide bismuth-213 from its parent solution of actinium-225. The breakthrough of the actinium-225 for all three columns was well below the toxicity level but the Isolute SCX and Isolute SCX-2 produced less of the bismuth-213 available on the column.
