镉离子对铅阳极电化学行为的影响

Effect of Cd^(2+) to Electrochemical Behavior of Lead Anode

应用循环伏安方法研究了铅电极在不同镉离子浓度含量的硫酸溶液中的阳极氧化行为 ,采用SEM、XRD方法观测了铅阳极阳极氧化形成的硫酸铅晶粒大小及二氧化铅的结晶结构。结果表明 :溶液中的镉离子对铅转化为硫酸铅有较大影响 。

WT5”BZ] The anodic oxidation behavior of lead electrode in the sulphuric acid solution with different Cd 2+ concentration by the method of cyclic voltammetry was investigated.The method of SEM,XRD was adopted.It was observed that the size of lead sulphate crystal formed by lead anodic oxidation and the structure of lead dioxide crystals.The results indicated that Cd 2+ in solution had take effect in the process that lead changed to lead sulphate and it had obviously no effect in the crystal structure and morphology of lead dioxide.
