Abstract

We studied the adsorption efficiency of steelmaking slag in removing volatile organic compounds (VOCs) for increasing the recycling rate of steel-making slag. Ceramic filter was prepared by mixing the steel-making slag and the diatomite which is used as adsorbents due to the advantage of the high specific surface area and regular mesopores. The adsorption efficiency for VOCs removal was about 80%, 96% and 85% in acetaldehyde, formaldehyde and ammonia, respectively. The adsorption efficiency over 80% for all The gases showed the practical possibility as the adsorption filter.

본 연구에서는 제강슬래그의 재활용 범위를 확대하기 위하여 제강슬래그를 접촉여재로 활용한 유기화합물의 흡 착성능을 평가하였다. 또한 표면에 미세한 기공을 가지고 있어 흡착여재와 여과필터로 많은 연구가 되어온 규조토를 제강 슬래그와 혼합하여 세라믹 여재를 만들고 유기화합물 흡착 특성을 평가하였다. 유기화합물로는 아세틸알데히드, 포름알데히드, 암모니아 기체를 사용하였으며, 각각 80%, 96%, 85%의 흡착 효율을 나타내었다. 사용된 모든 기체에 대해서 80% 이상의 흡착효율을 나타내어 흡착여제로의 활용 가능성을 확인할 수 있었다.
