Adsorption of phenol, o-, m-, p-cresol and benzyl alcohol has been measured from their aqueous solutions on activated carbon at 278, 298 and 323 K in their complete solubility range. An anomalous temperature dependence of adsorption of these compounds has been observed. Desorption measurements at 278 K show that the adsorption is not reversible in the lower concentration range. This behaviour, as well as the anomalous temperature dependence, has been attributed to chemical transformations which the adsorbed species undergo on the activated carbon surface. tion of phenol, o-, m-, p-cresol and benzyl alcohol has been measured from their aqueous solutions on activated carbon at 278, 298 and 323 K in their complete solubility range.
