摘要
用循环伏安法分别表征了Mn2 + 在酸性介质中和中性介质中的氧化还原性质。Mn2 + 氧化时 ,部分生成Mn3 + ,部分生成MnO4 -,光谱电化学实验也证实了这一点。高价锰还原时 ,在酸性溶液中可直接还原为Mn2 + ,但在中性溶液中 ,要经历MnO2 阶段。
Redox properties of Mn2+ in acidic and neutral medium were characterized using cyclic voltammetry.After oxidation of Mn2+ partial product was Mn3+ and another was MnO4-，which was also proved by the spectroelectrochemical experiment.When reduction of Mn species with high valency took place in acidic solution，the product was Mn2+,but in neutral medium MnO2 was the intermediate.
