| Outline of Final Research Achievements |
In this research, vermiculite was selected for a specimen as one of layered silicate salts. Vermiculite was suspended in water and Cs was doped. Various salts were mixed with the Cs-doped vermiculite in solid (powder) state and microwave was irradiated, which was found effective for Cs removal.
Addition of KCl and CaCl2 was effective for the ion exchange of Cs. And it was found that microwave heating has better removal effect than by an electric furnace below 700oC. It was also found that addition of these salts increases the permittivity and electric conductivity, which is related with the better microwave heating characteristics. Further addition of CaCO3 improves the removal effect, however, microwave heating became less easy.
