Outline of Final Research Achievements

Ruthenium, one of the useful elements contained in high-level liquid waste (HLLW), was expected to be converted into resource by separation and recovery. On the other hand, ruthenium complexes were important materials as dye for dye-sensitized solar cell.
In this study, a new separation and recovery process of ruthenium from HLLW constructed by using novel sulfur-containing diamide and hydroxyl oxime extractant-impregnated macroporous silica-based adsorbents. In addition, an available dye for dye-sensitized solar cell was synthesized from the recovered ruthenium. These results indicated the possibility of effective reuse of HLLW for energy generation.
