METHOD FOR ELECTROCHEMICAL CLEANING OF CHROMIUM-CONTAINING SOLUTIONS AND SEWAGE FROM IONS OF HEXAVALENT CHROMIUM

摘要

Using electrochemical purification of solutions from hexavalent chromium ions by restoring them on a flow-through volume-porous cathode in electrolysis with a cathodic and anode spaces separated by a porous septum. Before the restoration, a mesh of electrically conductive corrosion-resistant material is placed close to the septum and the anode potential is applied to it 1 silt
