Abstract

Transport mechanisms of nickel ion through a continuous electrodeionization (CEDI) were investigated in terms of electric properties of ion exchange textile (IET). The porous plug model and extended Nernst-Plank (N-P) equation were applied for the description of transport mechanism of nickel ion. The model revealed that the CEDI performance was mainly due to the induced current not accelerated mobility by IET. This study also suggested that optimal operating conditions are attained with minimized electroregeneration region.

전기탈이온 장치를 통한 니켈이온의 이동메커니즘이 이온교환섬유의 전기화학적 특성을 이용하여 조사되었다. 포러스 플러그 모델과 확장된 넌스트-플라크 식이 니켈이온의 이동 현상의 해석을 위해서 적용되었다. 적용된 모델을 통해 전기탈이온 시스템의 성능증가는 이온교환섬유를 통해 변화되는 이동도에 기인하는 것이 아니라, 이온교환매개체의 자체 전도도에 의해 일어나는 전류 유발 효과에 의한 것으로 나타났다. 또한, 최적의 전기탈이온 공정운전이 최소화된 전기적 재생영역하에서 일어남을 본 연구를 통해 제시되었다.
