Abstract

/g), PE 바인더의 입자크기가 200 µm일 때 444 (m 2 /g), 20 µm일 때 940 (m 2 /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 m 2 /g. The specific surface area of PE binder was 444 m 2 /g and 940 m 2 /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.
