Experimental Study on Deep Purification and Separation of High Cadmium Cobalt Sulfate Pre electrodeposition Liquid and Electrodeposition
This article mainly studies the deep removal of cadmium from high cadmium cobalt sulfate electroplating solution using barium sulfide and electrowinning experiments.The results show that under experimental conditions of room temperature,200 times the amount of Cd using barium sulfide,and 4 hours of reaction,the cadmium content in the solution after cadmium removal meets the requirements of cobalt cathode solution,and the recovery rate of Co is 99.81%,which is relatively ideal,The use of barium sulfide in the pre electroplating solution of cobalt sulfate for cadmium removal is more effective,cost-effective,and feasible.The cadmium content in the cobalt plate obtained by liquid electrodeposition after cadmium removal meets the requirements of the grade Co9995,and the problem of traditional cobalt electrodeposition cathode and sulfuric acid system cobalt titanium based lead metal oxide coating anode plate application has been solved through optimization in the experiment.
