“…In the lead-tin anode is the reaction of oxidation of Cr +3 to CrO 4 -2 , and to a lesser extent the oxidation of the medium, so it is in this compartment where the etching bath regenerates For each of the separators used, the experimental setup is done in Figure 2. The reactor consists of two transparent glass bodies (1), each of whom shall be a compartment (anode or cathode). The volume of each compartment is 250 ml.…”

“…The electrode potential is related to the selectivity of electrochemical reactions, and is a complex parameter that depends on many factors such as current distribution, the electrical conductivity of the electrode and the electrolyte, and the concentrations of the reactants and products (1)(2)(3). Potentiostatic control is achieved using a potentiostat adjusts the potential of working electrode with respect to a reference electrode.…”

The key parameters in the control of an electrochemical reactor in operation are the potential of working electrode and the current distribution, which depend on many factors, among which include: the transfer, the hydrodynamic conditions and the total voltage of the cell, Uc. However, it is often impossible to monitor these parameters and we must resort to measure other parameters such as total intensity, (the electrode potential) and the total voltage of the cell. Thus in the control of an electrochemical reactor (or the operation of an electrochemical reactor) can be carried out by controlling one of three variables: the electrode potential, voltage or current total. In this paper works in potenctiostat mode determined the main parameters or figures of merit that characterize this type of reactor, which is designed first and then at laboratory pilot scale
