| Outline of Final Research Achievements |
Prussian blue (PB) was shown to be effective for the adsorption removal of radioactive cesium ions from radioactive contaminated water after the Chernobyl nuclear accident, and its use was also expected in the Fukushima nuclear power plant accident. However, since generally synthesized PB particles are nano-order size, it is very difficult to separate the PB particles that have adsorbed radioactive cesium ions and then have reached adsorption saturation efficiently from contaminated water, so they have not been applied to practical applications.
Therefore, in this study, we applied our immobilization technique of magnetic nanoparticles, and attempted to prepare a spherical adsorbent containing PB and magnetite which could be easily separated by magnetic force. We have succeeded in preparing a functional adsorbent having high cesium ion adsorbability and recoverable by magnetic force.
