Abstract

A rapid and efficient method termed micro liquid-liquid extraction combined with concurrent solvent recondensation-large volume injection-GC-MS has been developed for the extraction and determination of PAHs in water. Some condition parameters were optimized to obtain high detection sensitivity. Calibration curves of 18 PAHs were linear in the range of 0.1-10 ng•L 1, with the correlation coefficients (r2) between 0.9993 and 1.0. The method attained good precisions from 0.3% to 4.5% for PAHs standard solutions. The method recoveries ranged between 64.5-119.5% for spiked with 5.0 ng•L 1 and 76.2-119.5% for spiked with 25.0 ng•L 1 and 50.0 ng•L 1 for real water samples. Limits of detection (LODs, S/N=3) of the method were determined from 0.010-0.068 ng•L 1. The optimized method was successfully applied to the determination of 18 PAHs in real water samples.
