Outline of Final Research Achievements

Ferrocyanide, such as prussian blue (Fe4[Fe(CN)6]3), captures radioactive cesium, but it does not work as a decontamination agent in water because it does not dissolve. We developed a new ferrocyanide hydrogel-complex (called ferrocyanide-complex, FC). The FC is stably dissolved in water because it contains a water-soluble polymer. When the polymer in FC is distributed, 31% of cesium is captured. On the other hand, 81% of cesium is captured in just 1 hour when the FC becomes a nanoscale sphere. The FC has been tested as a cesium capturing material and is important in the Fukushima recovery effort.
