摘要

提出了一种分离钴离子(II)和铁离子(III)的方法，并研究了它们同时存在于溶液中的情况。该方法采用pH = 2.3的碱性沉淀法对铁部分进行初步分离，得到铁和钴同时沉淀的产物，并采用非选择性磺酸阳离子树脂KU-2-8阳离子交换浸出法提取其中的钴。

Separation of ions of cobalt (II) and iron (III) with use of nonselective sulfonic cation resin KU-2-8

A separation method of ions of cobalt (II) and iron (III) has been proposed and studied for the case of their simultaneous presence in a solution. This method includes preliminary separation of an iron portion by alkaline precipitation with pH = 2.3, obtaining the product of simultaneous precipitation of iron and cobalt and extraction of cobalt from it by the method of cation-exchange leaching with the use of nonselective sulfonic cation resin KU-2-8.
