Apatite sequestration of technetium
| DWPI Title: Method for sequestering technetium in e.g. soil, involves introducing stannous modified apatite containing specified amount of tin into material, and contacting technetium with modified apatite such that technetium is absorbed |
| Abstract: A method for sequestering technetium is disclosed. The method includes contacting technetium with apatite under reducing conditions whereby the technetium is absorbed by the apatite. |
| Use: Method for sequestering technetium in soil, groundwater, streams, container, materials and fluids. |
| Advantage: Technetium is sequestered efficiently and economically. Apatite barrier is effectively formed in the presence of reducing agent. |
| Novelty: Method for sequestering technetium involves introducing a stannous modified apatite containing 0.1-0.5 mol% tin into a material, and contacting technetium with the stannous modified apatite such that technetium is absorbed by modified apatite. |
