Abstract:
In this study, large pore ordered mesoporous carbon (LP-OMC) material was first applied as solid-phase microextraction (SPME) coating for the extraction of polycyclic aromatic hydrocarbons (PAHs) from aqueous media. The LP-OMC SPME fiber was prepared via the dip-coating method in-combination with evaporation-induced self-assembly (EISA) approach. The LP-OMC coating material possessed large specific surface area with the BET surface area of 629 m2 g-1 and uniform large pore size at the mean value of 13.5 nm with a narrow pore-size distribution. The extraction performance of LP-OMC fiber for PAHs was compared with another kind of OMC fiber with pore diameter of 4.1 nm. The results implied that the LP-OMC fiber showed better extraction capability towards PAHs. The developed LP-OMC-SPME method for PAHs exhibited wide linear ranges (0.01-50 μg L-1), low detection limits (1.6-10.0 ng L-1) and good repeatabilities (3.9-7.4% for one fiber, 6.7-11.7% for fiber-to-fiber). The method was successfully applied for the analysis of PAHs in real environmental water samples with satisfactory recovery ranging from 82.6% to 112.1%.
