Abstract
The present invention relates to a method of capturing radioactive species in an aqueous solution and removing the radioactive species for disposal. The method includes the steps of providing a macroporous bead form sequestration resin including a sequestration ligand coupled to a sulfonic acid based polymer resin, subjecting the bead form sequestration resin to radioactive species contained in the aqueous solution to allow the bead form sequestration resin to capture the radioactive species; using an acid to lower a pH of the resin to release the radioactive species; and disposing the radioactive species in a radioactive storage facility.
