Title
Removal of Phenol Compounds by Clay Adsorbents
김정배Jeung Bae Kim,이태관Tae Gwan Lee
Abstract
This batch adsorption experiments were conducted to remove the organic phenol compounds with naturally abundant adsorbents such as zeolite, bentonite and kaolinite. A adsorption characteristics of organic pollutants such as phenol, 4-chlorophenol and 2,4-dichlorophenol with adsorbents were tested. To elucidate the surface characteristic of adsorbents, the zeta potentials were measured. As a result of zeta potential data, zeolite and bentonite indicated that the surface potentials seem to be independent on the pH and the low negative charge showed in the range of all pH, otherwise, the surface potentials of kaolinite affected by the pH. As a result of adsorption by using adsorbents such as zeolite, bentonite and kaolinite, phenol was removed more than 80∼90% in the range of pH 4∼9, and 4-chlorophenol and 2,4-dichlorophenol were removed about 60∼70% in the range pH 5∼8.
