Outline of Final Research Achievements

Cesium ions (Cs+) were successfully scavenged out of aqueous solution with nanosheet materials comprising an ion-exchenged pottasium titanate (K2Ti2O5) and further immobilized in the form of a crystalline cesium titanate (CsxTi8O16) via electorolytic processes in molten molybdate (MoO3) salts. The developed process involving the Cs ion scavenging through solidification in crystalline titanates can be applied to the backend of radioactive wastes of light-water reactors.
