Abstract
PURPOSE: To efficiently obtain a CoO4 soln. by electrolytically dissolving Co using an aqueous sulfuric acid soln. as an electrolytic soln., the Co as an anode and a material with low hydrogen overvoltage as a cathode while keeping the pH and cathode current density at specified values.
CONSTITUTION: Metallic Co is electrolytically dissolved using an aqueous sulfuric acid soln. as an electrolytic soln., the metallic Co as an anode and a material with low hydrogen overvoltage such as Ti, graphite, stainless steel or Ni as a cathode while keeping the pH at ≤1, the cathode current density at ≤5.6W2.8×pH A/dm2 and the temp. of the electrolytic soln. at ≤40°C. The resulting CoSO4 soln. is evaporated, concd., and cooled to obtain CoSO4.7H2O crystals.
