“…[28][29][30][31] With the high selectivity that it provides natively, much research work has been performed with materials containing β-cyclodextrin as adsorbents, as recently reviewed by Crini. 32 Tzou and co-workers also used it to develop an SPE method for determination of digoxin and metabolites in human serum. 33 However, its usage in SPE to concentrate phenolic compounds for analysis based on its inclusion property has not been reported.…”

A β-cyclodextrin bonded silica was synthesized by using a convenient method, and was evaluated as a selective sorbent for the solid-phase extraction of 4-nitrophenol and 2,4-dinitrophenol. When double-distilled water was used as the sample matrix, the sorbent showed a strong capacity to adsorb 4-nitrophenol and 2,4-dinitrophenol; the recoveries were found to be 96% and 99%, respectively, with a 1 L water sample. The selectivity of the sorbent was investigated by using a washing step with methanol. Most of the phenols were washed out with 5 mL of methanol, while 4-nitrophenol and 2,4-dinitrophenol still gave recoveries of 94% and 90%. The solution for efficiently eluting the analytes was optimized and the effect of the inorganic salt on the extraction was examined. In order to investigate the potentiality of the sorbent in dealing with real water samples, water from Donghu lake (Wuhan, China) spiked with nine phenolic compounds at microgram per liter levels were preconcentrated on this cartridge.

“…Due to their relatively hydrophobic cavity, CD are capable of forming inclusion complexes (IC) with variety of organic molecules and thus, CD can be effective for the removal of hazardous molecules from the surroundings by inclusion complexation (Crini and Morcellet, 2002;Olah et al, 1988;Landy et al, 2012;MorinCrini and Crini, 2013;Schofield et al, 2012). In our previous studies, we have demonstrated that CD functionalized polymeric NF can be potentially used as molecular filters for the air and water filtration by removing organic molecules from the required environment (Kayaci et al, 2013;Kayaci and Uyar, 2014;Uyar et al, 2009Uyar et al, , 2010aUyar et al, , 2010b.…”

“…Owing to this intriguing supramolecular mould, CD can form non-covalent host-guest inclusion complexes (IC) with a variety of molecules so they are particularly applicable in various field such as pharmaceuticals, functional foods, cosmetics, home/personal care, textiles etc (Blach et al, 2008;Flaherty et al, 2013;Harada et al, 2011;Hedges, 1998;Shao et al, 2010;Szejtli, 1998). Some molecules that CD form IC can be hazardous and polluting chemicals, so CDs are fairly useful for filtration/separation/purification areas (Olah et al, 1988;Crini and Morcellet, 2002;Landy et al, 2012;Morin-Crini and Crini, 2013;Schofield et al, 2012). For this purpose, it can be considered that, CD have also potential for the elimination of VOCs from the environment (Favier et al, 2011;Mauri-Aucejo et al, 2012).…”

In this paper, we reported the molecular entrapment performance of hydroxypropyl-beta-cyclodextrin (HPβCD) and hydroxypropyl-gamma-cyclodextrin (HPγCD) electrospun nanofibers (NF) for two common volatile organic compounds (VOCs); aniline and benzene. The encapsulation efficiency of CD samples were investigated depending on the various factors such as; CD form (NF and powder), electrospinning solvent (DMF and water), CD (HPβCD and HPγCD) and VOCs (aniline and benzene) types. BET analysis indicated that, electrospun CD NF have higher surface area compared to their powder form. In addition DMA measurement provided information about the mechanical properties of CD NF. The encapsulation capability of CD NF and CD powder was investigated by 1H-NMR and HPLC techniques. The observed results suggested that, CD NF can entrap higher amount of VOCs from surroundings compared to their powder forms. Besides, molecular entrapment efficiency of CD NF also depends on CD, solvent and VOCs types. The inclusion complexation between CD and VOCs was determined by using TGA technique, from the higher decomposition temperature of VOCs. Finally, our results were fortified by the modeling studies which indicated the complexation efficiency variations between CD and VOC types. Here, the inclusion complexation ability of CD molecules was combined with very high surface area and versatile features of CD NF. So these findings revealed that, electrospun CD NF can serve as useful filtering material for air filtration purposes due to their molecular entrapment capability of VOCs. © 2015 Elsevier Ltd

“…An aqueous alcohol, such as methanol, solution is often used as the mobile phase for CD columns in inclusion chromatography [11]. An updated review of the synthesis of CD-containing adsorbents was given by Crini and Morcellet [12]. There are primarily two types of synthetic CD-containing particles for such applications.…”

Cyclodextrins (CDs) are a family of cyclic-oligosaccharides with usually 6-8 glucopyranose units. Because of their unique donut-shaped steric structure they are able to form inclusion complexes selectively with some guest molecules. CDs are in starch-like powder form and are soluble in water to certain extents. It is desirable to produce insoluble CD-containing particles for adsorption, liquid chromatography and other applications. This work presents a novel method of synthesizing CD-containing resins. Resins synthesized with this method possess high contents of CDs and some favorable physical properties. Adsorption isotherms for three small aromatic compounds, namely phenylalanine, tryptophan and aspartame, were obtained experimentally.
