Abstract
An extensive experimental study of adsorption of various surfactants f rom aqueous solutions on four different activated carbons is reported. Both adsorption isotherms and the accompanying heats of adsorption ar e investigated. A theoretical description of the mechanism of adsorpti on in these systems is proposed, based on a model of multi-site occupa ncy adsorption on an energetically heterogeneous surface. Its utility is verified by a simultaneous quantitative fit of experimental adsorpt ion isotherms and the related heats of adsorption.
