Research output: Chapter in Book/Report/Conference proceedingConference contribution


Membrane capacitive deionization (MCDI) has emerged as an energy efficient desalination technique for treating brackish water by potential induced electro sorption of dissolved salt ions in aqueous solutions onto porous carbon electrodes. Most MCDI materials research has focused on porous carbon electrodes and alternatives to them. In this work, we explored MCDI performance with different ion-exchange membrane chemistries and intrinsic electrochemical properties. The results demonstrate that thinner and better conducting membranes enabled improved thermodynamic efficiency of MCDI.
