Kinetic Features of Cd and Zn Cathodic Formations in the Membrane Electrolysis Process

Chromate and dichromate solutions used for the activation passivation of cadmium zinc galvanic coatings metal products are widely due to their ability form corrosion-protective films. Therefore, in this article, we examined kinetic features cathodic deposition Cd Zn during membrane electrolysis. As a result comprehensive experimental theoretical studies, depositions were analyzed under different hydrodynamic conditions submembrane zone an anolyte. Experimental physicochemical methods such as analysis solutions, analytical modeling, statistical research. A regression dependence evaluating reaction rate constant was assessed based on least-square approximation proposed model. result, peculiarities formations electrolysis process analyzed. The effect mechanical mixing with values Reynolds number cathode evaluated. change Cd2+ Zn2+ ion concentrations also considered Overall, obtained results increased by 2.2 times using active environment
