The adsorption behaviour of 4-chlorophenol from aqueous solution to activated sludge — was quantitatively characterized in this paper. The effects of the initial pH values, initial chlorophenol concentration and adsorbent dosage on bloadsorptlon were investigated. The maximum adsorption capacity was found to be 110.5 mg/g at 100 mg/L iniiial concentration. The Freundlich and Langmui r adsorption isotherms were applied to describe the biosorption processes and the isotherm constants were evaluated.
