활성탄소천 전극을 이용한 NaCl과 NaF 용액에서 축전식 이온제거
Capacitive Deionization of NaCl and NaF Solutions with Activated Caron Cloth Electrodes
Electrosorption is defined as potential-induced adsorption on the surface of charged electrodes. After polarization of the electrodes, ions are removed from the electrolyte solution by the imposed electric field and held in electric double layers formed at the surface of electrodes. Unlike ion exchange, no chemicals are required for regeneration of the system, hence no secondary waste is generated. In this study, experimental electrosorption of ions from aqueous NaCl and NaF solutions were conducted using activated carbon cloth electrodes and the effects of distance between electrodes, applied voltage and electrolyte concentration on the electrosorption capacity have been investigated.
