SORPTION OF AROMATIC-COMPOUNDS IN WATER USING INSOLUBLE CYCLODEXTRIN POLYMERS

Insoluble beta-cyclodextrin (beta-CD) polymers have been used for the recovery of various organic pollutants from aqueous solutions. These r esins have been prepared by polymerization using epichlorohydrin (Epi) as a crosslinking agent. Several crosslinked polymers with various de grees of beta-CD were used. Several studies (time, concentration, kine tics, and pH) are presented here. The results show that these sorbents exhibit high sorption capacities toward substituted benzene derivativ es. The mechanism of sorption is both physical adsorption in the polym er network, and/or the formation of an inclusion complex and/or the fo rmation of hydrophobic guest-guest interactions.
