dc.description.abstract | A NO3--selective carbon electrode coated with an anion-selective polymer with polystyrenic macroporous nitrate-selective A520E resin particles (in chloride form; particle size: 300-1200 mu m) was fabricated for desalination of municipal wastewater and NO3- recovery during membrane capacitive deionization (MCI). Several issues, such as electrosorption/regeneration efficiency, selectivity of NO3-, and removal from real wastewater, were addressed to demonstrate the suitability of coated electrodes. The NO3--selective electrode induced better electrosorption than the conventional MCDI, whereas its salt adsorption capacity was lower than that of the ion-exchange (IX) layer only coated one. The mole fraction of NO3- adsorption kept increased even after saturation by replacing Cl- adsorbed on the resin coating layer. However, the desorption efficiency of NO3- was retarded as it was exchanged with Cl- and temporarily intercepted in the resin of the IX layer, during ion migration towards the bulk brine solution. 81.5% of NO3- was removed with better NO3- selectivity from real municipal wastewater, and a high concentration of NO3- brine was obtained through successive operation. However, the poorly selective NO3- desorption, which limits its enrichment due to the reverse ionic-strength gradient induced by the high concentration brine, needs to be mitigated to prove its effective recovery. | - |
