Macroporous polyamines containing β‐cyclodextrin (β‐CD) are used for the recovery of various organic pollutants from aqueous solutions. Several insoluble polyamines with various degrees of β‐CD were prepared. Studies concerning the sorption kinetics, the effect of pollutant concentration, pH of the solutions, and β‐CD content are presented here. The results of sorption experiments show that these sorbents exhibit high sorption capacities toward substituted phenolic derivatives. The mechanism of sorption is both physical adsorption in the resin polymer network through acid–base interactions, ion exchange, and hydrogen bonding due to the amino groups and the formation of an inclusion complex due to the β‐CD molecules through host–guest interactions, and hydrophobic interactions such as guest–guest interactions. © 1999 John Wiley & Sons, Inc.
