A benzyl functionalized ionic liquid, 1-benzyl-3-methylimidazolium bis [(trifluoromethyl)sulfonyl]imide ([BeMIM][Tf₂N]), was synthesized and characterized as an extraction solvent of dispersive liquid-liquid microextraction (DLLME) for enrichment and determination of 5 organophosphorus pesticides (phoxim, fenitrothion, chlorpyrifos, phorate and parathion) and 2 aromatic compounds (chloronaphthalene and anthracene) from environmental water samples by high-performance liquid chromatography (HPLC). [BeMIM][Tf₂N] had higher extraction efficiency than 1-octyl-3-methylimidazolium bis [(trifluoromethyl)sulfonyl]imide and common organic solvents such as CCl₄ and C₂Cl₄. The extraction was performed using 40 μL of [BeMIM][Tf2N] and 1 mL of methanol as extraction solvent and dispersive solvent respectively with centrifugal time of 5 min. Under the optimal conditions, the method proposed here provided a good linearity for all analytes with correlation coefficients between 0.9994 and 0.9998. The repeatability values, described as intra-day and inter-day relative standard deviations (RSDs) of five replicate experiments at three different concentrations of 10, 40 and 100 μg/L, were 1.1%-4.3% and 0.8%-4.8%, respectively. The limits of detection (LOD) were 0.01 μg/L-1.0 μg/L at a signal-to-noise ratio (S/N) of 3. This developed method was convenient and speedy, and could be employed to detect the analytes in three real environmental water samples with satisfactory relative recovery of 82.7%-118.3% and RSD of 0.7%-5.6%. Introduction of benzyl group into the imidazolium could obviously enhance the extraction efficiecny for analytes due to the π-π interaction between [BeMIM][Tf₂N] and analytes. [BeMIM][Tf₂N] was a satisfactory extraction solvent with a high enrichment factor of 339 and extraction efficiency of 81.4%. Partition coefficients of all analytes in [BeMIM][Tf₂N]-DLLME system were determined and the extraction mechanism was discussed.
