Abstract: Tandem electrodialysis (ED) cell systems and methods for using the tandem ED cell systems to extract and recover ions from ion-containing solutions are provided. The tandem ED cell systems are composed of ion-extraction and ion-recovery ED cells. A redox couple contained in the anolyte of the ion-extraction ED cell is different from a redox couple contained in the catholyte of the ion-extraction ED cell. The electrode reactions in the ion-extraction ED cell are reversed in the ion-recovery ED cell, with the anolyte and catholyte of the two ED cells swapped and continuously circulated. As a result, the redox species in the anolyte and catholyte of the two cells are never depleted, which allows for achieving ion extraction and ion recovery with the use of a minimal amount of the redox couples.
