Carbon electrodes have been successfully synthesized and characterized for desalination system based on Capacitive Deionization (CDI) technology. The carbon electrodes were synthesized with an activated carbon (700 – 1400 m2/g), carbon black, glutaric acid and polyvinyl alcohol as a binder using cross-linking method at 120 °C. The study was to investigate salt removal percentage value of 0.1 M NaCl, MgCl and KCl using CDI cell. A solution with 0.1 M was supplied to the cell using a Boyu Submersible pump (model SP-601) at a flow rate of 10 mL/min. When potentials of 1.0, 2.0, and 3.0 V were applied to the CDI cell, the result showed that a solution of 0.1 M KCl has greater salt-removal percentage than the solutions with 0.1 M NaCl and MgCl. The salt-removal percentage of KCl was achieved at 55% for 3.0 V whilst resulted in 20 and 30% for NaCl and MgCl, respectively.
