Methods for extracting radioisotopes from radiologically contaminated waste

Abstract

Methods are provided for separating radioisotopes from spent ion exchange resins used to process nuclear waste. In some embodiments, the resin is contacted with an aqueous solution including one or more acids to elute the radioisotopes into an enriched solution. In some embodiments, the resin is contacted with an aqueous solution including one or more salts, such as a sulfate or nitrate salt solution, to elute the radioisotopes into an enriched salt solution. The enriched solution can include at least
