The Removal of Arsenic(Ⅲ) from Acid Mine Drainage by Mineral Trap of Tooeleite (Fe6(AsO3)4SO4(OH)4·4H2O)

摘要：

　　The remediation with high concentration of As(Ⅲ) adopted Mineral Synthetic Immobilization Technology to remediate acid mine drainage and provided a novel pathway of removing As(Ⅲ) in form of tooeleite (Fe6(AsO3)4SO4(OH)4·4H2O).Results showed that the low pH environment benefited the formation of tooeleite.The scanning electron microscope images showed the morphology of the mineral.The result of infrared spectroscopy revealed that the AsO3 unit exited in the tooeleite structure and X-ray photoelectron spectroscopy confirmed that the valence of arsenic is +3.The arsenic release from tooeleite under acidithiobacillus ferrooxidans condition measured for the stability evaluation.
