Abstract：Activated carbons were deashed and modified by nitric acid and water vapor in order to fabricate electrodes for electrosorption tests. The electrosorption performance was tested in a capacitive deionization (CDI) system. The specific surface area and pore volume were increased by secondary activation, and the adsorption volume increased from 2.92 to 4.55 mg/g. The extent of activation was influenced by the activation time and activation temperature. The optimum activation time was found to be 1 h, and the adsorption volume increased with increasing temperature.
