| Outline of Final Research Achievements |
Since the explosion accident at the Fukushima nuclear power plant, decontamination of a huge amount of soil polluted with radioactive cesium became the urgent issue. These Cs isotopes stay as ions in the soils near the ground surface for a long period, since they are strongly fixed in the interlayer spaces of clay minerals. Because vermiculite clay has an extremely high adsorption capacity for Cs ions compared to other minerals, it can play an important role in the environmental fate of radioactive cesium in the polluted area. In the present work, we have elucidated the state of Cs ions fixed in a vermiculite clay, and examined the possibility of desorption of Cs ions.
