Electrodialysis is a common process which is widely applied for water purification and desalination or/and chemical species recovery. Solving the fouling of ion-exchange membranes is the bottleneck of this technology for stable processing along with low maintenance at large scale. This work aims to design combined electrodialysis/anodic oxidation (ED–AO) using as-prepared Pb/PbO₂ anode to boost the oxidation of organic dye (methyl orange, MO) and overcome the issue of AMX membrane fouling. Hybrid ED–AO process works synergistically to accumulate, by ion-exchange reaction, MO species in the anodic Pb/PbO₂ oxidative compartment to be oxidized and mineralized. As compared to single ED, excellent oxidation rates and membrane anti-fouling activities were found in ED–AO process. The characterization of the AMX membrane in single ED shows that the fouling was the main issue behind the low oxidation rate, causing a significant increase in the cell's electrical resistance, unlike in hybrid ED–AO process. Most of operating parameters including applied current density, initial concentration of MO, pH, supporting electrolyte (Na₂SO₄) concentration were investigated. The mechanistic pathways of MO oxidation and anti-fouling activity were discussed in depth. Through ten recycling tests, hybrid ED–AO process showed excellent stability and performance.
