Inverted capacitive deionization (i-CDI) for water purification can be considered the reverse of CDI, characterized by intermittent operation: ion-sorption (short circuit) and subsequent regeneration (charging). This new growing i-CDI technology needs to overcome the following: low performance electrodes, short lifetime, and low energy and cost-effectiveness. The efficiency and kinetics of the continuous salt removal process via i-CDI can be improved significantly by optimizing electrodes. In this study, we attempted to synthesize high performance electrodes. The activated carbon was functionalized for incorporation of positive charge and negative charge. The general properties (FT-IR, TGA, CV, zeta potential, etc.) of the electrodes will be presented in detail along with the electrodes-based i-CDI cell performance. |
