| Outline of Final Research Achievements |
The research introduces new approaches for the selective removal of radionuclides of different half-lives from the liquid matrices via selective isolation followed by concentration from bulk waste. We developed two techniques for the selective separation of Cs and Sr from the aqueous matrix using ion-selective solid-phase extraction assemblies. During the project tenure (FY2017 to FY2019), the research results that so far obtained either from the current project or related research theme in progress in my laboratory have been reported in peer-reviewed journals resulting in 20 articles altogether. Several presentations in international conferences also used to share the preliminary results from the research project.

| Academic Significance and Societal Importance of the Research Achievements |
The research was aimed to address the radiological issues for Fukushima’s revitalized future after the FDNPP accident. The findings can be used to treat radioactive waste from nuclear power plants or the health sectors. Government personnel dealing with regulatory issues can also use it.
