چکیده

Poly(octadecyl acrylate) with a terminal reactive group was synthesized by radical telomerization in various solvents. The polymers were grafted onto porous silica for use in RP-HPLC, and the molecular recognition ability was investigated along with the selectivity for the structural isomers of polycyclic aromatic hydrocarbons. The mechanism of selectivity was also investigated with differential scanning calorimetry and NMR spectroscopic observations.

SEPARATION OF POLYCYCLIC AROMATIC HYDROCARBONS WITH MIXED MICELLAR HIGH PERFORMANCE LIQUID CHROMATOGRAPHY

Separation of Polycyclic Aromatic Hydrocarbons was performed by RP-HPLC using mixed micellar mobile phase. Effect of temperature, types and amounts of coorganic solvent in mobile phase on efficiency, asymmetry factor and selectivity factor showed that the appropriate condition for separation of these compounds was 3% isopropanol (V/V) as co-organic solvent in mobile phase at 40°C. Analysis of...

Determination 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...

Retention behavior of large polycyclic aromatic hydrocarbons on metalloprotoporphyrin-silica stationary phases.

The retention behavior of large polycyclic aromatic hydrocarbons (LPAHs) (> or = 7 rings) on newly developed metalloplotoporphyrin (MProP)-silica stationary phases is examined and the results are compared to previously reported data for retention of the same solutes on commercially available phases. HPLC columns packed with FeProP-silica are shown to exhibit unique shape selectivity for LPAH re...

Synthesis 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...
