摘要
本文提出了一个测定钴的新方法。以钴标准溶液为滴定剂 ,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。具有灵敏、准确。
A new method of determining cobalt is described Platinum electrode is used as an indicator electrode,while the calomel electrode as a reference electrode.Cobalt of standard solution is used as titrant.The end point of tirtrantion is indicated by the sudden change of electric potential.The new method is sensitive precise and speedy.
