Actual industrial passivation baths of cadmium and zinc galvanic coatings applied as anode chambers. The cathode chamber contained sulfuric acid 1 % solution and a titanium cathode (BT-0). A window was cut in one of the walls with a RALEX®CM-PES 11-66 cation exchange membrane placed in it. The lead (С-0) was used as the anode. A comparative analysis of the performance of these technological baths before and after the using cation exchange membrane electrochemical devices was carried out. As a result of long-term experimental studies, the ecological and economic feasibility of their use was proven. popup.nrat_date 2025-03-24 Close
