Abstract
Heterogeneous ion exchange membranes were prepared by mixing polyethylene as matrix with bead and fibrous anionic ion exchangers at different mixing ratio. Generally, ion exchange capacities were increased with increasing the ratio of the fibrous ion exchanger content. The highest ion exchange capacity of the membrane was 1.86 meq/g at 30 wt% IXF (ion exchange fiber) in the membrane. The water uptake, fixed ion concentration, and ion transport number of the membrane increased with increasing the content of the fibrous ion exchanger. However, the electrical resistivity of the membrane was decreased with increasing the content of the fibrous ion exchanger. The lowest electrical resistivity of 5 Ω/cm(2) was observed at 30 wt% of IXF.

본 연구는 폴리에틸렌 기재에 비드와 섬유상 이온교환체의 배합비를 달리하여 불균질 이온 교환막을 제조하였다. PE 불균질 이온교환막의 이온교환능은 섬유상 이온교환체의 양이 증가할수록 선형적으로 증가하였으며 30 wt%에서 최대 1.86 meq/g 이었다. 불균질 이온교환막의 함수율, 고정이온농도 및 이온운반율도 섬유상 이온교환체의 양이 증가할수록 증가하였다. 반면 불균질 이온 교환막의 전기저항은 섬유상 이온교환체의 양이 증가할수록 감소하였으며, IXF (ion exchange fiber)의 혼합량이 30 wt%에서 5 Ω/cm(2)으로 전기저항 값이 가장 낮았다.

Keywords: heterogeneous ion exchange membrane; bead ion exchanger; fibrous ion exchanger; polyethylene; ion exchange capacity
