Prevention of Hydrosphere Contamination with Electroplating Solutions through Electromembrane Processes of Regeneration
The work studies the process of Cd2+ and Zn2+ cations transfer through a RALEX (R) CM-PES 11-66 cation-exchange membrane and the cations reduction as metals on the cathodes at the cathode chambers of the electrochemical units with a view to prevent the hydrosphere contamination with the electroplating solutions. Electrolysis of the solutions that imitated the possible composition of the passivating baths contained 50 g/l sodium dichromate, 10 g/l sulfuric acid and impurity ions of Cd2+ and Zn2+ in various concentrations. The designed passivation solutions with certain amount of impurity ions in the colour solution were forcibly mixed. The impact of the impurity ions concentration in the colour solution and of a forced mixing on the metal reduction was studied. Regularity in the increased metal reduction dependent on the metal concentration was found and the conditions favouring the ion migration through the cation-exchange membrane due to forced mixing were defined.
