Adsorption of Phenol by Activated Carbons Based on Fossil Coals of Various Degrees of Metamorphism

The adsorption of phenol by activated carbons obtained by the alkaline thermolysis (KOH, 800°C) of fossil coals of various degrees of metamorphism (C daf = 70.4–95.6%) was studied. Kinetic dependences and adsorption isotherms were obtained at initial concentrations of ≤3 mg/cm 3 (25°C). The rate con...

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