초록
알루미늄 제조 공정에서 부산물로 발생되는 적니와 제지슬러지를 이용하여 휘발성 유기화합물을 제거하기 위한 흡착제 개발 연구를 수행하였다. 흡착제의 제조를 용이하게 하기 위해 고밀도폴리에틸렌과 저밀도폴리에틸렌을 이용하였다. 흡착제에 고밀도폴리에틸렌을 사용한 것이 저밀도폴리에틸렌을 사용한 것 보다 비표면적 값이 높아서 흡착량이 증대되었다. 제조된 흡착제의 비표면적 값이 활성탄과 비교하여 상대적으로 매우 낮은 값 (
Recycling method of red mud, byproduct from the aluminium manufacturing process, and paper sludge was investigated in order for them to be utilized as the adsorbent for the removal of volatile organic components(VOCs). Either high density polyethylene(HDPE) or low density polyethylene(LDPE) was added to facilitate the manufacture of adsorbents. The utilization of HDPE in the adsorbents increased the adsorption capacity due to the good physical properties, such as, BET and true density, compared with LDPE. BET values of the manufactured adsorbents were much lower than the commercial activated carbon (
