摘要
在NH_3-NH_4Cl-H_2O体系下加入组合添加剂进行锌电积,考察极距、电流密度、电积时间和初始锌离子浓度对电流效率和阴极锌表面形貌的影响。结果表明,在极距3cm、电流密度400A/m^2、电积时间4h、初始锌离子浓度40g/L的较优条件下,锌电积电流效率超过95%,阴极锌表面致密平整。
Zinc was electrodeposited in NHa-NH4Cl-H2O system with combined additives. Effects of electrode distance, current density, electro-winning time, and initial concentration of zinc ions on surface morphology and current efficiency of zinc electro-winning were investigated. The results show that current efficiency is 95% above with smooth and dense surface morphology of cathode zinc under the optimum conditions including electrode distance of 3 cm, currency density of 400 A/m2 , initial concentration of zinc ions of 40 g/L, and electro-winning time of 4 h.
