Abstract
In this study, a solvent-assisted dispersive solid-phase extraction (SA-DSPE) method followed by a gas chromatography equipped with a flame ionization detector (GC-FID) was applied for the extraction and determination of some polycyclic aromatic hydrocarbons (PAHs) in various real samples. N,N′-bis(salicylidene)ethylenediamine (salen), as a sorbent, was simply synthesized and characterized. Under the optimal conditions (solution pH: 6.0, amount of sorbent: 0.5%, disperser solvent type: acetonitrile, disperser solvent volume: 500 µL, and centrifugation condition: 3743 g for 3 min), preconcentration factors and extraction recoveries for PAHs were obtained ranging from 140 to 183 and 70 to 92%, respectively. Linear dynamic ranges were from 2.0 to 200.0 ng mL−1 with the regression coefficients (R2) exceeding 0.99, limits of detection from 0.6 to 0.9 ng mL−1, and the repeatability values (RSD%) ≤ 8.4% (n = 5). The proposed method can be effectively applied for extracting and determining PAHs in both food and environmental samples.
