Sorption of dibenzofuran derivatives from aqueous solutions by beta-cyclodextrin polymers: an isosteric heat approach.
Crosslinked polymers containing beta-cyclodextrin units have been used to remove dibenzofuran and three of its derivatives from aqueous solutions close to their saturation concentrations. The temperature dependence behavior for the compounds analyzed shows significant differences, attributable both to the influence of the polarity of their substituents and to the heterogeneity of the sorbent, since the cyclodextrin cavity sites are more favorable for interaction with the sorbate molecules than the crosslinking network.
