| Outline of Final Research Achievements |
Stable energy resource supply is very important for Japan. Then, some researches for recovering the dissolved uranium from seawater progressed in Japan. However, the concentration of uranium in seawater is extremely low (ppb level), therefore, the highly efficient adsorbents capturing ppb-level uranium from seawater was desired. For this, we utilized the hydrogel as a new adsorbent base material for capturing uranium and other target elements. In order to demonstrate the usefulness of the hydrogel, we developed the amidoxime groups or crown ethers incorporated hydrogels and examined the ppb-level target elements capturing efficiency in the presence of other elements. From the experimental results, the potential for this purpose was demonstrated by considerably high adsorption functionality.
