Figure 1: Experimental cell with electrochemical apparatus. A; Ag/AgCl electrode. B: Membrane system (Monopolar or Monopolar + Mosaic membranes). Membranes parts are fixed by two rubbers with holes, 1 cm in diameter from both sides to avoid the leak of solution. C: Ag/AgCl electrode. D: 3 M KCl in agar.
