氯化钴溶液铅污染的研究

Research on Pollution of Cobalt Chloride Electrolyte by Lead

针对氯化钴溶液电积，在未向电解体系中添加任何含铅物质时，铅含量总是高于标准这一问题进行了研究。研究发现。

In view of the problem that lead content in the cobalt chloride electrolyte during electrowinning is always higher than that specified in the standard without addition of any leadbearing material, we conducted relevant research and found that the root for this problem is use of PVC electrolytic cell.
