Sorption behavior of Co $^{2+}$ on manganese oxide formed by reduction of MnO $_{4}$ $^{-}$

Kato, Tomoaki ; Onuki, Toshihiko; Saito, Takumi*; Yu, Q.

To develop a technology for recovering radioactive Co, we investigated the formation mechanism of Mn(IV) oxide (biomasss-MnO $_{x}$ ) prepared using bacterial cells as reducing agent and sorption behavior of Co $^{2+}$ on biomasss-MnO $_{x}$ . We found that biomasss-MnO $_{x}$ sorbs more Co than the MnO $_{x}$ prepared using lactic acid as reducing agent and the Co sorbed on biomass-MnO $_{x}$ was oxidized to Co(III).
