This work is focused on the separation of a daughter radionuclide .sup.221Fr from medicinal .sup.225Ac to provide a source of pure .sup.221Fr fraction for other studies. To achieve such a goal, diglycolamide extraction agents were immobilized on polymer matrix and tested in extraction chromatography experiments. Particularly experiments with N,N,N',N'tetrakis2-ethylhexyldiglycolamide in nitric acid medium provided promising results and the material was further studied in column experiments. The chosen conditions of separation provided .sup.221Fr in yields over 65% with .sup.225Ac contamination under 1% in less than 5 min, which is a sufficient proof of concept suitable for further studies.
