Activated carbon felts, which were prepared by the pyrolysis of phenol resin(Kuraray Co.), were used as the electrode of electrochemical deionization(ECD). The phenol carbon felts are divided into three ones due to the different sorts of specific surface area, which are nearly 1000 to 2000m2/g. The pore size and distribution and surface microstructures of the carbon felts were investigated. The relationship between their physical properties and electrode properties was also investigated. The evaluation of the electrochemical behaviors was performed by the cyclic voltammogram and impedance spectroscopy in 0.5M NaCl solution. In addition, adsorption properties of ions in the presence of diluted sea water were measured by the self-fabricated ECD equipment at constant voltage of 1.2 ~ 1.5V. The order of capacitive deionization rates for phenol carbon felt electrodes was as follow; FT-15 < FT-20 ≤ FT-15, which was a similar tendency with the results of electrode properties. |
