Popis:	The adsorption of phenol by activated carbons obtained by the alkaline thermolysis (KOH, 800°C) of fossil coals of various degrees of metamorphism (Cdaf = 70.4–95.6%) was studied. Kinetic dependences and adsorption isotherms were obtained at initial concentrations of ≤3 mg/cm3 (25°C). The rate constants of absorption of the adsorbate, maximum and specific capacities for phenol, and their dependences on Cdaf were determined. The main processes of the interaction of phenol with surface adsorption centers are discussed.
