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.

Sorption properties toward substituted phenolic derivatives in water using Macroporous polyamines containing β-cyclodextrin

Solid-state nuclear magnetic resonance (NMR) techniques were used to characterize cyclomaltoheptaose (β-cyclodextrin, β-CD) polymers. These insoluble materials have been investigated by cross-polarization magic angle spinning with dipolar decoupling (CP/MAS), magic angle spinning without dipolar decoupling (MAS), and high-resolution magic angle spinning with gradients (HRMAS). These NMR spectra allow the assignment of the principal 1 H and 13 C signals. The presence of two distinct components (cross-linked β-CD and polymerized epichlorohydrin) in the materials was clearly demonstrated. These polymers were used as sorbents and the resulting NMR spectra are presented and discussed.

Solid‐state NMR characterization of cyclomaltoheptaose (β‐cyclodextrin) polymers using high‐resolution magic angle spinning with gradients

This paper deals with inclusion compound formation between β-cyclodextrin (β-CD) and bifonazole, an antimycotic hydrophobic imidazole derivative. High performance liquid chromatography (HPLC) was used in order to measure the solubility of this drug as a function of the quantity of cyclodextrin in the samples. According to the classification of Higuchi and Connors, an A type solubility diagram was obtained, revealing the formation of soluble inclusion compound(s). Differential scanning calorimetry (DSC) was used for the first time, in order to draw binary phase and Tammann diagrams between β-cyclodextrin and bifonazole. The experimental results demonstrated the formation of two binary compounds, β-cyclodextrin–bifonazole and (β-cyclodextrin)i–bifonazole (where 2 < i < 3). The two compounds have been characterised using solid state nuclear magnetic resonance (NMR) spectroscopy. Different NMR spectra have been obtained, which indicate that the first compound is an inclusion compound and the second may be a crystallised compound, in which the bifonazole is not necessarily included in the cyclodextrin internal cavity.
