| Outline of Final Research Achievements |
The decontamination rate of about 60% has attained for the cesium contamination soil of the Yamakiya Kawamatamachi Elementary School schoolyard by electrophoresis method at which the soil was ground preliminary with the citrate using the planet ball mill. In the pilot scale experiment conducted in the local experiment, the decontamination rate of 70% was obtained against 5 kg of contaminated soil. About the porous aluminum electrode used for the electrophoresis apparatus, the cesium occlusion capability inside an electrode was investigated for the pseudo-contaminated water which used the stable isotope cesium chloride. As a result, electric occlusion of the cesium is promptly carried out with application of voltage, and even if the occluded cesium makes polarity of an electrode reverse, it is not released, and it can be expected as cesium contamination water treatment technology.
