Abstract
A method of purifying a high specific activity Sn-117m composition is provided that includes extracting an iodide complex of Sn-117m with an organic solvent from an acidic aqueous cadmium solution comprising a dissolved irradiated cadmium target, an acid, and a source of iodide. The organic solvent layer comprising the iodide complex of Sn-117m is substantially reduced in cadmium content. The Sn-117m may be back extracted into an aqueous solution.
