| Research Abstract |
In this study, adsorption behavior of Co and actinides(Th(IV), Np(V), U(VI)) on biogenic Mn oxide was examined. Compared with abiotically synthesized Mn oxidδ-MnO2, biogenic Mn oxide showed rather contrasting adsorption behavior. The specific adsorption behavior of the biogenic Mn oxide was possibly attributed to the structural difference between biogenic Mn oxide andδ-MnO2, and organic ligands released from microorganisms.
