| Outline of Final Research Achievements |
This study aimed to develop novel radioactive waste management method, in which target radionuclides can be immobilized on and/or enclosed in carbon nanotube (CNT), by using supercritical hydrothermal synthesis treatment. Aqueous solutions containing both various metal ions such as uranium and lanthanides and CNT were treated under supercritical conditions, and the concentrations of each metal ion were analyzed due to several spectroscopic instruments. These results showed that nanocomposite materials composed by the CNT and the metal oxides could be successfully recovered. This method would be suitable to radioactive waste management.
