ABSTRACT: The sorption properties of films on bases of chitosan and sodium carboxyl methylcellulose (Na-CMC) with toluene have
been checked. The sorption rate, sorption thermodynamics and isothermal
properties of toluene molecules in chitosan/Na-CMC
films are analyzed by adsorption-calorimetric method. Thus, it was found that toluene is adsorbed on the chitosan/Na-CMC film
by the same patterns of sorption of aromatic compounds, due to the process of
penetration of toluene molecules into the network of chitosan macromolecules
and this is preceded by the absorption process by the surface of the
chitosan/Na-CMC film.
