Abstract

The isotherms of sorption of six organic pollutants (phenylmethanol (benzyl alcohol), phenol, cyclohexanol, o-xylene, toluene and cyclohexane) from water solutions onto zeolitic tuff (Si/Al ratio = 2.4) have been determined by batch experiments at 25 °C, in 1.0∙10-3 mol dm-3 Tris-HCl buffer, pH 6.0. The solutions were analyzed by gas-chromatography. The best description of the experimental data was given by the Freundlich equation, whose constants have been determined and compared with literature data.
