Technetium-99m extraction and transport across tri-n-octylamine-xylene based supported liquid membranes

Extraction of pertechnetate with bicyclic guanidinium compounds has been studied in the KTcO4-buffer-H20/ligand-trichloromethane system Extraction data of guanidinium ligands have been compared with trialkylmethylammonium (Aliquat 336), tetraphenylphosphonium and tetraphenylarsonium chloride. The lipophilicity of extractants investigated was determined by RP-HPLC. The efficiency of pertechnetate extraction correlates with the lipophilicity of the guanidinium compounds. 1:1 complex formation in the organic phase was observed. The influence of hydroxide, chloride and bicarbonate on the pertechnetate extraction has been investigated. Pertechnetate is extracted with great preference over OH-, CI-and HCO3-, ions.
