CAPTURE, REMOVAL, AND STORAGE OF RADIOACTIVE SPECIES |
| 摘要 |
A method of capturing radioactive species from an aqueous solution and removing the radioactive species for disposal, includes: contacting the aqueous solution with a first sequestration resin comprising a sequestration ligand coupled to a sulfonic acid based polymer resin backbone, to allow the first sequestration resin to capture the radioactive species; removing the first sequestration resin with the captured radioactive species from the aqueous solution; and using an acid to lower a pH of the first sequestration resin to release the radioactive species from the first sequestration resin. |
