同槽电解二氧化锰和锌的研究

Formation of Manganese Dioxide on the Anode while Electrodepositing Zinc on the Cathode in the Same Electrolyser

本文用极化曲线的方法研究了在锌电极上各种添加剂对氢发生电位的影响。从中选择了几种添加剂用于同槽电解二氧化锰和锌,提高了阴极电流效率。对同槽电解二氧化锰和锌的工艺条件也进行了研究。

Polarization curves of zinc in 25 g/l H2SO4 electrolyte with various additives has been studied. Some additives applied to the electrolyser containing MnSO4 and ZnSO4 electrolyte were selected. As a result of this study the current efficiency of electrodepositing zinc had been raised. The technology of electrochemical formation of manganese dioxide and electrodepositing zinc -in the same electrolyser has been established.
