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.

活化轮胎热解炭对苯酚和氯酚的吸附性能

在间歇系统中研究了活性轮胎热解炭（ATPC）对水溶液中苯酚（Ph），4-氯苯酚（4CP）和2,4-二氯苯酚（DCP）的吸附，包括动力学和平衡。使用不同的动力学模型和吸附等温线来描述酚的吸附行为。动力学研究表明，该过程可以用伪二级模型来描述。Sips等温线获得了平衡吸附数据的最佳拟合结果。所选酚在所有吸附剂上的吸附量按Ph <4CP <DCP的顺序增加。还研究了离子强度和pH值对吸附的影响。结果表明，ATPC可用作吸附剂，用于从水溶液中去除苯酚。
