Process and apparatus for separating tritiated water |
| abstract |
A process and apparatus for separating tritium from an aqueous solution that contains one or more additional dissolved radionuclides is disclosed. In accordance with the process the aqueous solution as a first liquid phase is contacted with each of three layers as a solid phase within a column. A first layer comprises particles having a plurality of pendent methylene diphosphonate groups. A second layer comprises strongly basic anion exchange particles, and a third layer comprises polymer particles free of ionically charged groups. The contact is maintained until a second liquid phase is formed that contains tritium as substantially the only radionuclide, and that second liquid phase is collected and can then be counted to determine the amount of tritium present. The column with its three layers constitutes the separation apparatus. |
