Abstract

Nitrogen oxide (NOx) is one of the highly toxic acid gases. In this study, EDA-VBC-S-DVB compound, which is an amine modified terpolymer, was used as a NOx gas adsorption removing material and it was prepared by changing the amount of crosslinking agent in order to evaluate the NOx gas adsorption capacity. Adsorption experiment was carried out with the variation of adsorption time and NOx gas supply capacity. The NOx gas adsorption capacity was quantitatively estimated by the application of XPS analysis and it increased with the amount of crosslinking agent and the NOx gas supply capacity. EDA-VBC-S-DVB compound prepared in this study showed 12.96 mL·h for the critical point of the NOx gas supply capacity, 1.2182 mmol/g for the maximum value of the NOx gas adsorption capacity, and 392% for the maximum value of the NOx gas relative adsorption capacity


NOx 가스는 발생원이 다양하며 높은 독성을 갖는 산성가스 중 하나이다. 본 연구에서는 삼원 공중합체에 아민그룹을 개질시킨 EDA-VBC-S-DVB를 NOx 가스 흡착 제거 물질로 사용하였으며 가교반응에 따른 흡착성능을 비교분석하기 위해 가교제 첨가량을 변화시키면서 제조하였다. NOx 가스 공급용량을 변화시키며 흡착실험을 수행하였으며 XPS 정량분석을 통해 EDA-VBC-S-DVB의 NOx 가스 흡착용량을 평가하였다. 가교제 첨가량과 NOx 가스 공급용량에 따라 NOx 가스 흡착용량이 증가하였으며 본 연구에서 제조한 EDA-VBC-S-DVB의 경우 NOx 가스 공급용량 임계치는 12.96 mL·h, NOx 가스 흡착용량 최대치는 1.2182 mmol/g, NOx 가스 상대 흡착용량은 392%를 보여주었다
