“…In addition to inclusion complexation, hydrogen-bondings, p-p interactions, hydrophobic interactions and steric repulsion are assumed to be responsible for chiral recognition. Feng et al [87] described the preparation of silica-based phases containing b-CD derivatized with 8-quinolinol as a chiral selector. Several CD CSPs are commercially available (Astec, Whippany, NJ, USA).…”

This review gives a survey of different chiral separation principles and their use in high-performance liquid chromatography (HPLC), gas chromatography (GC), supercritical fluid chromatography (SFC), thin-layer chromatography (TLC), capillary electrophoresis (CE) and capillary electrochromatography (CEC) highlighting new developments and innovative techniques. The mechanisms of the different separation principles are briefly discussed and some selected applications are shown.

“…The CDS was synthesized according to procedures given in our previous work. 29 An elemental analysis was performed with a Model-1106 elemental analyzer (Carlo Erba, Italy), which gave the percentage of carbon and hydrogen as 9.1, 1.0%, respectively. Thus, the β-cyclodextrin bonded on to the silica was estimated to be 0.158 mmol/g.…”

“…From our original work, 29,34,35 4-nitrophenol was found to be strongly retained by a β-cyclodextrin stationary phase. This implies that β-cyclodextrin has the possibility to be used as an excellent adsorbent for nitrophenols.…”

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.

“…Thus, it has found wide application as HPLC stationary phases for the separation of various compounds. [22][23][24] Feng and his coworkers have utilized β-cyclodextrin bonded silica as a selective sorbent for on-line solid-phase extraction of 4-nitrophenol. 25 The application of β-cylcodextrin in SPME has not been reported.…”
