Tóm tắt

This study focuses on fabrication of porous carbon electrodes which are used as the electrodes to treat
brackish water following Capacitive Deionization technology (CDI). Effect of conductor amount such
as graphitr or acetylene black on material properties as well as electrochemical behavior of the
composite electrodes were investigated. SEM images and results of N2 adsorption – desorption shows
that the composite electrodes have porous structure with many holes. The presence of Gt or AB
conductors enhanced the specific capacitance of the composite electrodes. The specific capacitance
reached 50.8 F/g and 53.9 F/g with the presence of 5% Gt or AB, which is higher nearly 2 times than
that of mAC electrode (27.8 F/g).
