摘要
研究了锌电积过程中杂质行为及其相互反应对电流效率的影响．在较高酸度下，电积过程中可接受的杂质浓度显著降低．在电解液含Ｚｎ４５ｇ／Ｌ，酸１２０ｇ／Ｌ时，对锌电积发生明显影响的杂质含量范围为：砷、锑≥０．３～０４ｍｇ／Ｌ，锗≥０．０４ｍｇ／Ｌ。
In this paper, the effects of impurities on the current efficiency in zinc electrowinning were investigated. The acceptable concentration of impurities were decreased a great deal when the acid concentration was high. The concentraton ranges of impurities that affected zinc electrowinging considerably were 0.3-0.4 mg / L As and Sb, 0.04 mg / L Ge and 3￣5 mg / L Co for the solution containing 45 g / L Zn and 120 g / H2SO4. The structure and photograph of the deposits were given.
