Abstract
In this study, Sulfonated PONF-g-styrene ion exchange fibers were synthesized by radiation induced graft copolymerization. And also, hybride ion exchange fibers, which was combined sulfonated PONF-g-styrene fibers and cationic ion exchange resin, were fabricated by hot melt adhesion method and then their adsorption properties were investigated. Ion exchange capacity and water content of hybrid ion exchange fibers increased as compared with those of bead and ion exchange fiber. Their maximum values were 4.76 meq/g and 23.5%, respectively. Adsorption breakthrough time for mercury of hybrid ion exchange fiber was slower than those of bead resin and fibrous ion exchanger. It's value was 130 minutes. Their breakthrough time become short as increasing of pH, and concentration. The initial breakthrough time was observed before and after 10 minutes as increasing of concentration. The adsorption of hybrid ion exchange fibers for Hg2+, Pb2+, Cd2+ among heavy metals in the mixed solution was observed before 20 min. And also, The adsorption for Hg2+ among the heavy metals by hybride ion exchange fibers was observed.

본 연구에서는 PONF에 스티렌을 방사선 조사에 의하여 그래프팅한 후, 설폰화시킨 이온교환섬유를 제조하였다. 또한 핫멜트 점착방식으로 이들과 비드 수지를 결합시켜 복합 이온교환섬유를 제조하고 이들의 중금속 흡착특성을 확인하였다. 설폰화 PONF-g-스티렌 이온교환섬유의 이온교환용량과 함수율은 비드나 단일 이온교환섬유에 비해 모두 증가하였으며, 이온교환용량과 함수율은 각각 최대 4.76 meq/g, 23.5%로 높게 나타났다. 또한 복합 이온교환섬유의 Hg2+ 흡착파과 시간은 130분으로 비드와 섬유상 이온교환체보다 매우 늦게 나타났다. Hg2+의 흡착파과 시간은 pH가 증가함에 따라 파과가 빠르게 진행되었으며, 농도가 증가함에 따라 초기 흡착파과는 10분 전후에서 일어났다. 복합 이온교환섬유의 혼합용액(Hg2+ Pb2+ ,Cd2+)에서의 흡착은 초기 20분 이내에 급격한 흡착 반응이 진행되었으며, Hg2+이 가장 빠른 흡착파과가 일어났다. 또한 온도 변화에 따른 복합 이온교환섬유의 중금속 흡착은 Hg2+이 가장 빠른 흡착이 이루어졌다.
