| Outline of Final Research Achievements |
Treatment of acid mine drainage with acidophilic iron oxidizing bacterium and production of biogenic iron oxide minerals were investigated. The futures of iron oxides, Schwertmannite and goethite, formed under various pH and temperature conditions with an acidophilic iron oxidizing bacterium “E10” were studied. The oxides were found to exhibit high adsorption of heavy metals, As(Ⅴ), Se(Ⅵ), and Mo(Ⅵ)
