Electrodialysis Cells Based On The Use Of Redox Mediators
Inventors: Kyoung-Shin Choi, Dohwan Nam, Dong Ki Lee
Electrodialysis cell systems for water deionization is provided. Also provided are methods for using the electrodialysis cell systems. The cells use the forward and reverse reactions of a redox mediator and the combined operations of a deionization cell and an ion-accumulation cell to enable sustainable deionization with a significantly decreased operating voltage, relative to conventional deionization cells. The cells have applications in seawater desalination, water purification, and wastewater treatment.
