At present,the environmental pollution of heavy metals and toxic organic pollutants has been widely concerned in the community.Some researches indicated that manganese-oxidizing bacteria widely existed in the environment can remediate Mn (Ⅱ) pollution and produce biogenic manganese oxides.The biogenic manganese oxides have weaker crystalline,smaller particle size,higher Mn valence,more cavity structure in octahedral,larger specific surface area,stronger adsorption,oxidation and photochemical reductive dissolution characteristics than that of the chemical Mn oxides.The biogenic manganese oxides can absorb Cu(Ⅱ),Zn(Ⅱ),Pb(Ⅱ),Co(Ⅲ),Cd(Ⅱ),Hg(Ⅱ),oxidize Co(Ⅱ),As(Ⅲ),Cr(Ⅲ),U(IV),Ce(Ⅲ),degrade ethynylestradiol and other organic pollutants.The biogenic manganese oxides are environmental materials with wide application prospect.
