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.
