In this work, an experimental analysis of toluene adsorption from water solution on an organo-zeolite-adduct and onto zeolitic tuff from water solutions was carried out. This material is an organo-zeolite made by irreversibly binding the humic acids onto natural zeolite. Isotherms for sorption of toluene from water solutions have been determined by batch experiments at 4, 14, 24 and 34 °C. For both materials, the sorbitivity was good, particularly so for organo-zeolite adduct. The parameters of the Freundlich equation and isosteric and standard sorption enthalpies are analyzed.

Abstract

In this work, an experimental analysis of toluene adsorption from water solution on an organo-zeolite-adduct and onto zeolitic tuff from water solutions was carried out. This material is an organo-zeolite made by irreversibly binding the humic acids onto natural zeolite. Isotherms for sorption of toluene from water solutions have been determined by batch experiments at 4, 14, 24 and 34 °C. For both materials, the sorbitivity was good, particularly so for organo-zeolite adduct. The parameters of the Freundlich equation and isosteric and standard sorption enthalpies are analyzed.
