摘要
提出了一个快速测定钴的电位滴定法。以钴标准溶液为滴定剂，用铂电极为指示电极，甘汞电极作为参比电极，利用电位的突变来指示终点。该法具有灵敏、准确、快速等特点。测定橡胶—金属粘合剂中的钴，结果良好。
A simple and rapid method for the determination of cobalt by potentiometric titration is described. The standard solution of cobalt is used as titrant, the platinum electrode as an indicator electrode , while the calomel electrode as a refer- ence electrode. The end-point of titration is indicated by the sudden change of electric potential. The new method is char- acterized by sensitivity , precision and quick.The good result could be obtained with this method for determinating Co (Ⅱ )in rubber-metallic adhesion agent.
