초록

본 연구에서는 실험실에서 합성한 ZrP와 상업용 Amberlite IRP-64, Amberlite IRC-718 이온교환 수지를 SBR과 Epoxy 결합제로 사용하여 EIX전극을 제조하고, 전극전위에 따라 제조한 EIX 전극에 대한 구리이온의 흡 · 탈착성능과 특성을 고찰하였다. 이온의 전달특성은 결합제의 종류에 따라서 가장 크게 영향을 받았으며, 흡착공정에서 최대의 흡착속도를 보이는 최적의 전극 전위가 존재함을 확인할 수 있었으며, 탈착공정에서는 사용한 수지와 금속이온의 흡착력에 의해서 가장 크게 영향을 미쳤다.

EIX electrodes containing cation exchange resins(ZrP, Amberlite) and binders(SBR, Epoxy) were fabricated in different drying conditions of various temperature and pressure. The performance and physical properties of those were measured and the adsorption and desorption kinetics in copper sulfate solution were investigated at the various electrode potentials. The ionic transport in EIX electrode was seriously affected by binder system. The maximum adsorption rate of copper was obtained at optimum cathodic potential. In elusion process, the desorption rate was significantly influenced by adsorpted force between the resin and the metal tons.
