초록
폴리스티렌을 acetyl sulfate 시약을 사용하여 술폰화시킨 후 다공성 양이온교환 막으로 제조하였다. 제조된 막의 특성을 분석한 결과 다공성의 형태를 가졌음을 확인할 수 있었고, IR 분석결과 술폰산기의 도입을 확인할 수 있었다. 전체적으로 반응물 중 황산의 양이 증가할수록 이온교환능력이 증가하는 경향을 확인할 수 있었고, 전기투석 공정에 적용가능성을 판단한 결과 양이온에 대한 선택성과 음이온에 대한 배제성을 간접적으로 확인할 수 있었다.
We prepared porous cation exchange membrane using polystyrene such as, EPS (expanded polystyrene), SAN (styrene acrylonitrile copolymer) and HIPS (high impact polystyrene). These three kind of polystyrene were sulfonated by acetyl sulfate to make sulfonated porous cation exchange membrane such as, SEPS (sulfonated expanded polystyrene), SSAN (sulfonated styrene acrylonitrile copolymer)and SHIPS (sulfonated high impact polystyrene). SEM was employed to validate porous structure of membrane, and IR spectroscopy was used to validate sulfonation rate of ion exchange membrane. As a results, ion exchange capacity was increased with an amount of sulfuric acid in reactants and cation exchange membrane showed the selectivity to a cation and showed the exclusivity to an anion.
