Capacitive Deionization Technology for Water Treatment

Dear Colleagues,

Capacitive deionization (CDI) is an emerging water purification technology, where the direct voltage applied on the electrodes enables ions or charged particles to form electric double layers (EDLs) on the surface of electrodes for the purpose of water purification. At present, capacitive deionization has been widely used in industrial, agricultural, and domestic water desalination and seawater desalination. The advantages of CDI are characterized by low energy consumption, environmental friendliness, high adsorption efficiency, and easy operation.

In addition to research on the adsorption efficiency of CDI, another fundamental research challenge, still unresolved as of today, is how to improve the adsorption selectivity of CDI—a challenge closely related to the separation, purification, and enrichment of ions in complex solutions.
