Abstract
In this study, adsorption properties of oxidized NO by plasma using aminated polyolefin-g-GMA hybrid anion exchange fibers were investigated. The maximum conversion of NO2 by plasma was 49% at the conditions of 200 ppm NO, 10% O2 and 30 L/min of flow rate. The adsorption content for NO2 of hybrid anion exchange fibers increased with increasing the swelling ratio and the highest value was 1.5 g H2O/g IEF. The adsorption of NO2 by hybrid anion exchange fibers were very fast until 10 min and reached its maximum value of 80% at 120 min. Ion exchange capacity of hybrid anion exchange fibers increased with increasing the swelling ratio and it showed the highest 0.6 mmol/g IEF values at L/D=5. The adsorption isotherm model for hybrid anion exchange fibers were closer to Freundlich than Langmuir adsorption isotherm model. It was shown that adsorption of the multimolecular layer was dominant.

본 연구에서는 아민화 polyolefin-g-GMA 복합음이온 교환섬유를 이용하여 플라스마 산화된 NO의 흡착특성을 고찰하였다. 플라스마 산화에 의한 NO2 전환율은 NO 200 ppm, 산소 10%, 유속 30 L/min일 때 최대 49%이었다. 또한 복합음이온 교환섬유의 NO2 흡착량은 함수율이 높을수록 증가하였고 함수율이 최대 1.5 g H2O/g IEF이었으며, 복합음이온 교환섬유의 NO2 흡착은 10분까지 빠르게 진행되었고 120분에서 최대 80% 흡착되었다. 이온교환 용량은 함수율이 증가함에 따라 증가하였으며, 흡착컬럼 충전 비가 L/D=5에서 0.6 mmol/g IEF로 가장 높았다. 또한 이온교환 섬유의 흡착은 Langmuir 등온흡착 모델보다 Freundlich 등온흡착 모델에 가까웠으며, 다분자층에서의 흡착이 우세하게 발생한 것을 확인할 수 있었다.
