内容記述 |
Radioactive liquid waste containing nuclear fuel materials and chemical reagents is being stored at Japan Atomic Energy Agency (JAEA) while a treatment method is being established. This waste includes uranyl nitrate solutions and organic solvents contaminated with uranium, which were generated during engineering-scale solvent extraction tests at the Engineering Demonstration Facility-1 (EDF-1) of JAEA. For removing nuclear fuel materials from the radioactive liquid waste to reduce the radioactivity of the waste, we developed RFIDA, a new perfluoroalkyl (RF)-based ligand with a basic structure of iminodiacetic acid (IDA). This study involved conducting an adsorption test byimpregnating RFIDA into porous silica with a polymer to confirm that the synthesized RFIDA adsorbs uranium. The distribution coefficient (Kd) of the RFIDA adsorbents in uranyl nitrate solution ranged from approximately 1 to 3. The results confirmed that RFIDA exhibits the ability to adsorb or elute uranium depending on the nitric acid concentration. |
