In this study, a CDI electrode was constructed using chemical activated carbon fibers (ACFs) and evaluated its salt removal efficiency. CDI unit cell was prepared with polyacrylonitrile based carbon fiber. ACFs were prepared by electrospinning, followed by oxidative stabilization, heat treatment and activation. The surface morphology change of ACFs was investigated by using SEM. The specific surface area and pore structure were evaluated by BET and DFT equations. Chemical activation with NaOH was achieved under various conditions to investigate the relationship between pore structure and CDI efficiency. |
