Abstract

The electro-electrodialysis process (EED) is used to generate H2SO4 and NaOH from sulphate sodium salt Na2SO4. The key phenomenon limiting the current efficiency of this process is the proton leakage through the anion selective membrane was not observed. The electro-electrodialysis was carried out with a three-compartment cell with two platinum-coated titanium electrodes separated by three compartments. The couple membrane used in this work is AFN and CMX. The experiments were carried out for four current densities 8.33 mA.cm-2 11.11mA.cm-2, 13.88mA.cm-2 and 27.77 mA.cm-2. For each current density, a voltage variation of cell and concentrations of H2SO4 and NaOH in the two compartments with the current density was used. The concentration of H2SO4 and NaOH increases with current density and with time, but higher for NaOH. The current efficiency increases with the current applied to the cell. The request for the electro-electrodialysis operation power was calculated in terms of the electrical energy consumed to produce H2SO4 and NaOH for 6 hours of electro-electrodialysis and it was found floating with the current applied and concentration sodium sulphate used and the concentration of H2SO4 and NaOH products, but is comparable for both initial concentrations of sodium sulfate.
