METHOD AND DEVICE FOR SEPARATING TECHNETIUM FROM TECHNETIUM-CONTAINING MOLYBDENUM AND PURIFYING SAME, AND METHOD AND DEVICE FOR RECOVERING MOLYBDENUM

摘要

Technetium-containing molybdenum is dissolved in a solvent so as to make a solution. The solution passes through a first column. The first column is loaded with an extraction chromatographic resin. The solution, which has passed through, including molybdenum and a solution, which is used for cleaning the first column, are mixed together as necessary to recover molybdenum. Subsequently, the first column allows an acid solution to pass through so as to elute technetium from the extraction chromatographic resin for recovery. This allows, for example, supplying Tc-99m alone separated from a target material turned into a solution after production using 100 Mo(p,2n) 99m Tc.
