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 oxidation reaction of Mn (OH) 2 with Mn Cl2, Mn SO4 and Mn (NO3) 2 solution under alkaline conditions was studied.The results of X-ray diffraction showed that the oxidation product was Mn3O4.The potential of -p The results of the reaction are analyzed in Figure H, and the change of p H value with time in the air oxidation of Mn (OH) 2 was measured and analyzed.
