中文摘要: 采用多种电化学研究方法探讨了在Zn电积过程中Co^2 对阴极极化过程的影响,并对其极化机理进行了研究。研究表明.当Co^2 浓度≥6mg/L时,产生严重的“烧板”现象,降低了阴极Zn沉积反应的交换电流密度,对Zn沉积反应起极化作用,而且严重影响锌的晶体形状。
中文关键词: Zn电积 阴极极化曲线 Co 交换电流密度
Abstract:There are multiple methods adopted to research the Co~(2+) ion effect on the cathodic process in zinc electronic deposition and it's kinetics. The results show that when the existence of Co~(2+) ion is more than 6mg/L, it not only reduces the exchanging current density in zinc electronic deposition reaction but also acts as polarization in zinc electronic deposition and makes a great bad effects on the process of zinc electrolysis.
