| Outline of Final Research Achievements |
In this work, heteropoly acids which form insoluble salts with Cs+ and Prussian blue analogues which selectively adsorb Cs+ were respectively dispersed and immobilized in silica gels and silica-alumina gels using freezing in order to obtain materials which allow the selective recovery of Cs+ existing in an extremely dilute state. Such materials were also molded into the form of microhoneycombs by controlling the direction of freezing in order to reduce the resistance they cause against fluid flows, and to significantly enhance their response speed towards Cs+ recovery.
