제목 Electrosorption Behaviors of Nitrate Ions
초록 Nitrate component is one of the major water quality problems due to their adverse effects on environment.
Electrochemical reduction or ion exchange technique has been used as a conventional method to remove the nitrate. But removal capacity by ion exchange is not so high to satisfy the unlimited release to the environment and electrochemical reduction have a drawbacks of operation at an high reduction potential. One of the efficient methods to treat the nitrate-containing waste is the electrosorption.
In this study, we conducted the experiments on the adsorption of nitrate component to investigate the application feasibility of the electrosorption technique using ACF as a good conductive electrosorption adsorbent. Electrosorption behaviors of nitrate component was investigated using a batchwise electrochemical cell. ACF felt used as a working electrode and an adsorbent were wound around a graphite rod(current collector) and dipped in the test solution. Effective removal is accomplished by applying a positive potential in the range of 0.5 to 0.9V(vs SCE) to ACF electrodes. Electrosorption of nitrate exhibits a strong pH dependence and is affected by existence of any other anions.
