Abstract

The adsorption of phenol (Ph), 4‐chlorophenol (4CP), and 2,4‐dichlorophenol (DCP) from aqueous solutions on activated tire pyrolysis chars (ATPCs) was studied in a batch system, including both kinetics and equilibrium. Different kinetic models and adsorption isotherms were used to describe the adsorption behavior of the phenols. The kinetic study shows that the process can be described by a pseudo‐second‐order model. The best fitting results for the equilibrium adsorption data were obtained with the Sips isotherm. Adsorption of the selected phenols on all of the adsorbents increased in the order Ph < 4CP < DCP. The effect of ionic strength and pH on the adsorption was also studied. The results show that the ATPCs could be used as adsorbents for the removal of phenols from aqueous solutions.
