Abstract Scope Over the past several decades electrodialysis membranes have been employed for the removal of metals from galvanizing industry effluents. For the technical viability, it is useful to know some properties of the system to avoid, for example, precipitation of inorganic salts, destruction of the membranes and an increase in the energy consumption. The scope of the presente study is to use the chronopotentiometry method to determine the limiting current density, transition time and resistence of the cationic membrane HDX 100 using a simulated solution of the galvanizing industry effluent prepared with copper sulfate and sulfuric acid in different concentrations: 0.1; 0.5 and 1.0 g/L of Cu2+. The current-voltage curves obtained have the three regions clearly defined, which makes possible determine the limiting current and the membrane resistence. The chronopotentiometric curves were also effectively constructed and transition times were determined, which comproves the success of the method used in this work.
