Abstract Scope |
Battery grade cobalt sulfate is an important raw material for the production of cathode materials for lithium-ion batteries. Crude cobalt sulfate solution often contains a variety of impurities. The existence of these impurities will affect the performance of cathode materials, so it needs deep purification and impurity removal. In this project, we used goethite and direct oxidation for adsorption to remove Fe, Cu, Pb, Cd, Cr and other impurity elements in cobalt sulfate solution. The result shows that the order of goethite adsorbing heavy metal ions is chromium, cadmium/nickel and cobalt. We used direct oxidation adsorption method to adsorb iron, chromium and copper ions from the solution. Under the conditions of pH value 4.0 and temperature 60℃, the removal rate of iron ions in the solution can reach 89%, which provides guidance for the study of adsorption and impurity removal of cobalt sulfate solution in the future. |
