Chemically bonded stationary phases that use synthetic hosts containing aromatic binding clefts: HPLC analysis of nitro-substituted polycyclic aromatic hydrocarbons.
نویسندگان
چکیده
The synthesis of hosts with improved binding affinities for nitroaromatic guests is described. Association constants for several host-guest complexes were measured in chloroform solution and ranged over three orders of magnitude. Two hosts were covalently linked to silica gel to produce chemically bonded stationary phases for HPLC. The use of these phases for HPLC analysis of nitro-substituted polycyclic aromatic hydrocarbons is discussed.

Strategies to Compare Bonded Stationary Phases of Hplc for the Preparative or Semi-preparative Separation of Unsaturated Polycyclic Hydrocarbons by Groups in Products Derived from Petroleum
This contribution summarizes methods to compare bonded stationary phases for the compound-class HPLC separations of unsaturated polycyclic hydrocarbons and polar compounds. These strategies are based on the physical chemistry behavior of the functional group of the bonded stationary phase, behavior of the unsaturated polycyclic hydrocarbons under isocratic and gradient elution, regression analy...
متن کاملPreparation, characterization, and performance evaluation of UiO-66 analogues as stationary phase in HPLC for the separation of substituted benzenes and polycyclic aromatic hydrocarbons
UiO-66 analogues are good candidates as stationary phase in HPLC because of their chemical/thermal stability, large surface area, and two cage structures. Here, two UiO-66 analogues, UiO-66-NH2 and UiO-67, were synthesized and used as stationary phase in HPLC to evaluate their performance in the separation of substituted benzenes (SBs) and polycyclic aromatic hydrocarbons (PAHs). The results sh...
متن کاملDetermination of Polycyclic Aromatic Hydrocarbons in Olive and Refined Pomace Olive Oils using HPLC/FLD
ABSTRACT: In this study, an analytical method is developed to determine 15 polycyclic aromatic hydrocarbons (PAHs) in olive and refined pomace olive oils using HPLC coupled with a fluorescence detector. The standardised method of ultrasound-assisted solvent extraction consisted of liquid–liquid extraction with organic solvent and purification on C18 and Florisil bonded-phase cartridges was modi...
متن کاملDetermination of Some Polycyclic Aromatic Hydrocarbons in the Caspian Seawater by HPLC Following Preconcentration with Solid-Phase Extraction
A solid-phase extraction (SPE) method for sample clean-up and preconcentration followed by reversed-phase high-performance liquid chromatography (RP-HPLC) with uv detection is reported for determination of polycyclic aromatic hydrocarbons (PAHs) in the caspian seawater. A good resolution was obtained using acetonitrile:water (40:60) as mobile-phase for separation of these compounds. The eff...
متن کاملSynthesis and Evaluation of L-glutamide Derived Carbonyl Group Containing RP-HPLC Phase for Polycyclic Aromatic Hydrocarbon (PAH) Separation
A new L-glutamide derived internal C=O group containing HPLC stationary phase was synthesized. The L-glutamide lipid was immobilized on to silica surface through aminopropyltrimethoxysilane (APS) linker. The detailed chemical structure of the compounds leading to the final lipid was characterized by melting point measurement, FTIR, H NMR and elemental analysis in each step. Chromatographic prop...
