Description
Summary:Various methods have been developed for the extraction of a promising medical radionuclide 117m Sn from proton-irradiated TiSb intermetallic compound, a target material suitable for irradiation with an intense beam of accelerated protons. To separate radiotin from Ti, Sb, and radionuclides of other elements, methods of ion-exchange chromatography and liquid extraction were used, in particular, the anion-exchange separation of tin and titanium in the form of a peroxide complex in HCl solution, extraction of tin with benzene from iodide solutions, and chromatographic purification on silica gel from citrate solutions. As a result, 117m Sn of high purity, which meets the requirements for nuclear medicine, was obtained.
