Resumo: There are different concepts in electrochemistry that must be supported by a laboratory practice to better understand their importance in industrial applications. This work reports the procedure for manufacturing an electrodialyzer in series of two or more compartments with easy manipulation. Likewise, it reports the results obtained by using this system in the nitrate elimination from synthetic NaNO3 solutions at different concentrations. Among other results obtained in the electrodialysis of these solutions, the one that stands out is the demonstration of the linear relationship between the limiting current, obtained from the polarization curves, and nitrate concentration. Additionally, implementation of the separation treatment shows that the time of elimination of practically all ionic species depends on their concentration in solution and ranges between 50 and 80 min.
