“…To accomplish this task, cyclodextrins can be crosslinked with reagents such as epichlorohydrin in order to obtain insoluble resins capable of adsorbing aromatic substances from aqueous solutions [3]. Cyclodextrin polymers have been successfully applied to the removal of diverse substances from aqueous solutions [4][5][6][7][8][9].…”

“…A 2.52×10 −4 -mol/l BB working solution was prepared from the stock solution by appropriate dilution. β-CDP, which has less background absorbance in ultraviolet and visible region and retains the inclusion characters of hydrophobic cavities of β-CD, was synthesized and characterized as earlier described (Yu et al 2003). The detailedly synthetic procedure was as follows: A 40 g of β-CD, 10 g of soluble starch, and 100 ml of 20% sodium hydroxide were added into a beaker.…”

A new and sensitive solid phase extraction (SPE) combined direct spectrophotometry for determination of brilliant blue (BB) in food has been developed, in which β-cyclodextrin polymer (β-CDP) is used as a SPE adsorbent to extract BB from aqueous solutions to form a solid supramolecular complex with a 1:3 molar ratio of BB to β-CDP, and BB in β-CDP was directly determined by a solid phase spectrophotometry. SPE conditions were pH 7.0, temperature 20°C, ionic strength 0.1 mol/l, and shaking time 40 min. The calibration curve is linearity in the concentration range of 0.05-12.0 μg/ml. The proposed method was applied to the determination of BB in food samples at 627 nm maximum absorption wavelength with satisfactory results.

“…6 As CDs' solubility in water limits their applications to some extents, there have been considerable research interest on insoluble CD contained polymers. 7,8 The technical route to prepare CD contained polymer focuses on either crosslinking of CD molecule with bifunctional agents, 9,10 or immobilizing CD molecule as pendant units on polymer chains. 11,12 Because CDs favor holding a guest molecule in their inner cavity, 13 those CDs contained polymers are widely used in molecular recognition, 14 separation, 15 drug delivery, 16 purification, 17 and sensors.…”

A novel insoluble bimodal porous polymer containing b-cyclodextrin (b-CD) was prepared to adsorb aromatic amine compound. The process involved copolymerization of styrene and methyl methacrylate with a maleic acid derivative of b-CD, subsequently, above formed copolymer was foamed by supercritical CO 2 . The chemical properties and physical structure of obtained copolymer was analyzed using Fourier transform infrared spectra, Thermal gravimetric analysis, X-ray diffraction, scanning electron microscope, and N 2 adsorption techniques. The inclusion adsorption of aromatic amine compounds on b-CD copolymer was carried out in a batch system. The quantities of aromatic amine compounds adsorbed on b-CD copolymer reached equilibrium within 60 min. The adsorption kinetic could be fitted to a pseudo-secondorder kinetic equation, and the linear correlation coefficients varied from 0.9828 to 0.9935. With the influence of molecular structure and hydrophobicity of the aromatic amine compound, the sequence of quantity of aromatic amine compounds adsorbed on b-CD copolymer is p-toluidine > aniline > benzidine > o-toluidine. The adsorption equilibrium data of aromatic amine compound adsorbed on b-CD copolymer were fitted to Freundlich and Langmuir models, respectively. The linear correlation coefficients of Langmuir model varied from 0.9516 to 0.9940, and the linear correlation coefficients of Freundlich varied from 0.9752 to 0.9976. It is concluded that Freundlich model fits better than Langmuir model, because the adsorption of aromatic amine compound on b-CD copolymer is a chemical process.
