摘要：Selective removal of monovalent and divalent ions from ternary solution, synthetic seawater, and real seawater is studied in an electrodialysis cell with iridium oxide as anode and cathode. The experiments were performed at two different current densities, 10 A m-2 and 100 A m-2. Sulphate was found to be difficult to remove at the lower current density (10 A m-2) while the cations were removed more efficiently at both current densities. The size, charge, and concentration of ions were found to be the main factors influencing the selective removal of monovalent or divalent ions. Scale formed in the recirculated electrolyte in the concentrate chamber could be removed upon treatment with 0.1 M citric acid.
