Abstract—Expanded graphite, which was prepared from natural graphite as a result of thermal treatment with
acids, was used for the removal of the anticonvulsive preparation carbamazepine from aqueous solutions. The
adsorption isotherm of carbamazepine was adequately described by the Langmuir, Temkin, and Freundlich
equations. The adsorption of carbamazepine under dynamic conditions was studied.
