New hydrophilic and insoluble polymers containing beta-cyclodextrin (beta CD) have been prepared by simple radical polymerization in water using 2-hydroxyethyl methacrylate (HEMA) as comonomer. Several copolymers with various degrees of beta CD were synthesized. A characterization was carried out using infra-red spectroscopy and Cross Polarization Magic Angle Spinning Nuclear Magnetic Resonance C-13 (CP/MAS NMR). The molecular mobilities of these polymers have been analyzed in terms of nuclear relaxation parameters such as C-13 spin lattice relaxation (T1) and H-1 spin lattice relaxation in the rotating frame (T1 rho). These new sorbents containing beta CD were then used for the recovery of various organic pollutants from aqueous solutions. The results of sorption experiments show that they exhibit high sorption capacities toward substituted benzene derivatives. The mechanism of sorption is due to the formation of an inclusion complex between beta CD and guest molecules.
