Abstract

The invention discloses production of nickel aminosulfonate or cobalt aminosulfonate through an ion exchange method; the production of nickel aminosulfonate or cobalt aminosulfonate through the ion exchange method relates to ion exchange resin, an ion exchange column, amino sulfonic acid, a pure alkali solution and deionized water. The production comprises the production steps of ion exchange resin transformation, adsorption, elution and the like. The implementation scheme having the advantages of simple process route, low cost and continuous production is provided for production of nickel aminosulfonate or cobalt aminosulfonate.

Description

technical field [0001] The invention relates to the production of electroplating-grade nickel sulfamate or electroplating-grade cobalt sulfamate by an ion exchange method, belonging to the field of electroplating chemistry. Background technique [0002] Nickel sulfamate and cobalt sulfamate are important electroplating main salt and catalyst raw materials. Widely used in electroplating industry and electroforming industry. Its existing production process includes: 1. Nickel (cobalt) salt is prepared into basic carbonate and then reacted with sulfamic acid to generate nickel (cobalt) sulfamate. The process includes complex unit operations such as synthesis, filtration, and washing. It is cumbersome and the process is complicated. 2. Metal and sulfamic acid generate nickel (cobalt) sulfamate under the action of catalyst. The catalyst used in its production is an oxidant, which cannot be completely removed, and can passivate the anode if the oxidant is used in excess for ele...
