초록

본 연구에서는 정수기용 필터로 사용되는 활성탄 블록을 압출 방법으로 제조할 경우 활성탄 블록의 비표면적에 영향을 미치는 고분자 바인더의 특성에 관하여 고찰하였다. 고분자 바인더로 사용되는 Polyethylene의 입자 크기를 변화하여 그에 따른 활성탄 블록의 비표면적의 변화 및 수용액상에서 염소 이온의 흡착 특성을 연구하였다. FE-SEM을 이용하여 PE의 입자 크기 및 입자의 모양을 분석하였으며, 질소 흡.탈착을 이용하여 활성탄 및 활성탄 블록의 비표면적을 측정하였다. 비표면적 측정결과 원료 활성탄은 1186 (m2/g), PE 바인더의 입자크기가 200 μm일 때 444 (m2/g), 20 μm일 때 940 (m2/g)로 측정되었으며, 필터 성능을 확인하기 위하여 염소 흡착 실험을 실시하여 정수 성능을 평가하였다.

This paper describes activated carbon block filters prepared by extrusion for water purifier. The specific surface area of the activated carbon blocks affecting the properties of a polymer binder were investigated. Polyethylene (PE) particles were used as a binder polymer and the effect of particle sizes on changes in the specific surface area of activated carbon blocks in addition to the adsorption properties of chloride anion in the aqueous solution were investigated. The sizes and shapes of PE particles were measured using SEM. The specific surface area of activated carbon was 1186 m2/g. The specific surface area of PE binder was 444 m2/g and 940 m2/g with the particle sizes of 200 μm and 20 μm, respectively. In order to verify the performance of the filter, chlorine adsorption experiments were conducted.

Keywords:activated carbon block;chloride;specific surface area
