ABSTRACT:
A process for preparing ceric sulphate in solution. A saturated solution of cerous sulphate is electrolyzed at a high anodic current density in the range 100 to 400 mamp/cm.sup.2, high cathode current density in the range 1000 to 4,500 mamp/cm.sup.2 and with vigorous agitation in the presence of dilute sulphuric acid. The process permits the production of concentrated ceric sulphate solutions at commercially viable current densities and efficiencies.
