Effect of Environmental Factors on Mn2+ Release of Δ-Mno2 in Water

摘要：

　　Manganese dioxide (MnO2) is one of the important sewage treating agents for adsorption of trace heavy metals due to its outstanding structural flexibility and novel chemical and physical properties.The δ-MnO2 is characterized by low points of zero charge,high negative charge and large surface areas.It is actively involved in various chemical reactions,thus it has a higher adsorption capacity for metal ions.In addition,the phenomenon of the release of Mn2+ during the adsorption of certain heavy metal ions onto δ-MnO2 has been followed with interest by researchers.Manganese-contaminated waters are becoming of environmental concern following increased awareness of the need for environmental protection.But the effects of Mn2+ release of δ-MnO2 on the environment are lacking in thorough and systemic studies so far.
