초록

방사선 전조사법에 의하여 폴리프로필렌 부직포 상에 2,3-에폭시프로필메타크릴레이트 (GMA)를 공중합시킨 후 다양한 혼합용매 상에서 이미노디아세트산 (IDA)과 반응시킴으로서 고성능의 섬유상 금속 흡착제를 제조하였다. 그라프트 반응시의 그라프트율은 반응시간과 반응온도, 총 조사선량 및 선량율에 의존하는 것으로 나타났다. GMA가 그라프트된 폴리프로필렌 부직포 상에 이미노디아세트산을 도입하는 아민화반응에 있어서 다양한 혼합용매가 반응성에 미치는 영향을 고찰한 결과 디메틸술폭시드 (DMSO)와 물을 적정비율로 혼합한 혼합용매 상에서 가장 높은 반응성을 가지는 것으로 나타났으며, 물만을 사용하는 경우 아민화반응은 전혀 진행되지 않았다. 이온농도 100ppm으로 조제된 중금속 용액에 제조된 아민화 흡착제를 일정시간 담그어 금속이온에 대한 흡착성능을 살펴보았는데, 각각의 경우에 대하여 흡착효율을 다음의 순서를 따랐다: 납 > 코발트 > 철.

The grafting of 2,3-epoxypropylmethacrylate (GMA) onto polypropylene fabric was carried out by the γ-ray preirradiation grafting technique. Subsequently, the GMA-grafted polypropylene fabric was reacted with iminodiacetic acid (IDA) in different mixed solvents to prepare the fibrous metal adsorbent. The grafting extent was found to be dependent on the reaction time, temperature, preirradiation dose and dose rate. The effects of various mixed solvents on the IDA amination onto GMA-grafted polypropylene fabric were investigated. Compared with other mixed solvents, the extent of amination was highest in the dimethylsulfoxide (DMSO)/water, but the reaction did not occur in the water. The adsorption characteristics of various metal ions by the prepared adsorbent were examined when it was immersed in the 100 ppm metal ion solution. The amount of adsorption followed the order: Pb²⁺ > Co²⁺ > Fe²⁺.
