2P-730 : Continuous braciksh water desalination via rocking chair capacitive deionization

Capacitive deionization (CDI) is an electrochemical desalination technology using porous electrode materials. Although it is considered as a high energy efficient and eco-friendly process, a separated released the absorbed ion step is requried in typical capacitive deionization system, and resulting in cost-intensive process. In this study, we investigated “Rocking chair capacitive deionization” that consists of two cation selective porous carbon electrodes and an anion exchange membrane, and it allowed a continuous process by a rocking-chair ion movement during constant current operation. Moreover, the RCDI has an efficient energy consumption and high salt adsorption capacity.
