Electrosorption: an alternative option for desalination

Electrosorption is generally defined as adsorption on the surfaces of charged electrodes by applying potential or current. Electrosorption deionization method is a low-pressure non-membrane deionization process, with the potential to be a low energy cost alternative for desalination in the future. In this paper, the principle and mechanism of the electrosorption deionization method are discussed, the materials and properties of the electrode used in electrosorption process are summarized and the application and prospect of this promising desalination method are reviewed.
