Abstract：
:Olive husk was used for the preparation of activated carbon by chemical activation with KOH. The effects of carbonization and activation time on carbon properties were evaluated. The surface area of the produced carbons was measured by means of N(2) adsorption at 77K. The carbons with the highest surface area were further characterized by means of elemental analysis, particle size measurement, Boehm titration, zeta potential measurement, and temperature programmed desorption (TPD). Subsequently they were used for adsorption of a mixture of polyphenols consisting of caffeic acid, vanillin, vanillic acid, pi-hydroxybenzoic acid and gallic acid at two temperatures, and their adsorptive capacity was compared to a commercial carbon Acticarbon CX and found to be higher enough. The role of the porosity and surface groups are discussed in relation to the adsorption forces and the properties of the adsorbed substances. A thermodynamic interpretation of the results is also attempted.
