Abstract

The sulfonated ion exchange fibers were synthesized by $Co^{60}\;{\gamma}-ray$ radiation-induced graft copolymerization. Degree of grafting was increased with increasing the total dose. The degree of grafting for POF-g-St/DVB copolymer was 1000%. The ion exchange capacity of sulfonated ion exchange fibers were increased by increasing the degree of sulfonation. Its maximum value was 5.06 meq/g. The ion exchange capacity of sulfonated POF- co-St/DVB ion exchange fiber was higher than that of the sulfonated POF- co-styrene ion exchange fibers. The amount of adsorption for heavy metals were also increased with increase in the degree of grafting of the ion exchange fibers.

[ $Co^{60}\;{\gamma}-ray$ ] 선원에 의한 그래프트 공중합 반응을 통해 설폰화 이온교환 섬유를 합성하였다. 그래프트 공중합 반응의 경우 총 조사선량이 증가할수록 그래프트율이 증가하였으며, 가교제인 divinylbenzene을 첨가하여 공중 합하였을 때 최대 1000%의 그래프트율을 보였다. 또한 이온교환 섬유의 설폰화율이 증가할수록 이온교환용량이 크게 증가하였고 가교제가 첨가된 설폰화 POF-co-St/DVB 이온교환 섬유의 이온교환용량이 5.06 meq/g로 설폰화 POF-co-styrene 이온교환 섬유에서 보다 높게 측정되었으며, 이온교환 섬유의 중금속 이온 흡착량은 섬유의 그래프트율이 증가함에 따라 증가하였다.
