| Outline of Final Research Achievements |
In this study, magnetic electroactive ion exchange particles with uniform sizes were synthesized and used for continuous separation and recovery of target metal ions such as cesium ions in a designed compacted electro-maganetic experimental equipment. The experimental conditions for continuous adsorption/ desorption of the target metal ions were optimized by investigating the effects of the initial concentration of target metal ions, the initial concentrations of coexisting ions, the amount of magnetic particles, the applied voltage and the electrode distance on the separation efficiency to the target cesium ion. In addition, the adsorption/desorption mechanism of magnetic electroactive particles for the target metal ions was clarified. Further, the recycle stability when repeatedly used was examined. Furthermore, a target metal ion continuous separation recovery system that can be put to the practical use was constructed theoretically.
