초록
본 연구에서는 정수슬러지를 원료로 사용하여 펠렛형 흡착제를 제조하고 질소흡착법, XRD, XRF 및 암모니아 승온탈착법 등을 사용하여 물리.화학적 특성을 분석하였다. 정수슬러지 유래 펠렛형 흡착제와 첨착활성탄의 암모니아 및 포름알데히드 기체의 흡착 성능을 비교하였다. 정수슬러지로부터 제조된 펠렛형 흡착제는 첨착활성탄보다 표면적과 기공부피는 훨씬 작지만 암모니아를 훨씬 더 많이 흡착할 수 있었다. 이는 정수슬러지로부터 제조된 펠렛형 흡착제 표면에 산점이 훨씬 더 많이 분포해 있어서 화학흡착에 의해 암모니아를 흡착하기 때문이다. 반면에, 산성가스인 포름알데히드 가스 흡착의 경우는 넓은 표면적과 발달된 기공으로 인하여 첨착활성탄의 흡착성능이 정수슬러지로부터 제조된 펠렛형 흡착제에 비해 훨씬 우수하였다.
In this study, a pellet-type adsorbent was prepared by using the water-treatment sludge as a raw material, and its physical and chemical properties were analyzed through N2-adsorption, XRD, XRF, and NH3-TPD measurements. Adsorption performance for gaseous ammonia and formaldehyde was compared between the pellet-type adsorbents prepared from water-treatment sludge and the impregnated activated carbon. Although the surface area and pore volume of the pellet-type adsorbent produced from water-treatment sludge were much smaller than those of the impregnated activated carbon, the pellet-type adsorbent produced from water-treatment sludge could adsorb ammonia gas even more than that of using the impregnated activated carbon. The pellet-type adsorbent prepared from water-treatment sludge showed a superior adsorption capacity for ammonia which can be explained by chemical adsorption ascribed to the higher amount of acid sites on the pellet-type adsorbent prepared from water-treatment sludge. In the case of formaldehyde adsorption, the impregnated activated carbon was far superior to the adsorbent made from the water-treatment sludge, which can be attributed to the increased surface area of the impregnated activated carbon.
