Abstract
전기 투석기 내에서 일어나는 이온 전달 현상을 고려하여 간단한 방정식을 세우고 이 식을 이용하여 전류-전압 곡선을 계산하였다. 이 방정식의 유효성을 확인하기 위해 실험실 규모의 전기 투석기를 제작하고 NaCl을 모델 전해질로 해서 실험후 전류-전압 곡선을 얻었다. 전기 투석기에 공급되는 전해질의 유속이 증가할수록 한계전류밀도가 증가하였고 이론에 의해 충실히 예측되었다.
Ionic mass transport in electrodialysis was modelled to describe current-voltage characteristics. Modelling equations were checked by the experiments conducted with a laboratory electrodialyzer. Sodium chloride solution was supplied to the dialyzer where current-voltage curves were generated. Limiting current density was increased with the increase of flow rate, which was also predicted by the model equations.
