摘要
研究了在碱性条件下 ,用 Mn Cl2 ,Mn SO4,Mn( NO3) 2 溶液生成的 Mn( OH) 2 的空气氧化反应 .X-射线衍射测定结果表明 ,氧化产物为 Mn3O4.用电势 -p H图对反应结果做了分析 ,测定并分析了 Mn( OH) 2 空气氧化过程中 p H值随时间的变化特征 .
The air oxidation of Mn(OH) 2 precipitated from MnCl 2,MnSO 4 or Mn(NO 3) 2 and NaOH is researched in alkaline medium.It is proved that the oxidation products of Mn(OH) 2 are Mn 3O 4 by the XRD.The reactions are further analysised by the standard eletrode potential pH diagram.The changing chacracter of pH of solution with the time during the process of air oxidation is determined and discussed.
