| Outline of Final Research Achievements |
In this study, adsorption of actinides on biogenic Mn oxide was investigated. Actinides were strongly adsorbed on inorganic Mn oxide without microorganisms, indicating that they were tightly fixed at the surface of Mn oxide. In contrast, adsortion of actinides on biogenic Mn oxide, mixture of Mn oxide and microbial cells, was lower than that on inorganic Mn oxide. The results of this study suggest that the mobility of actinides would increase in systems where minerals and microorganisms coexist.
