| Abstract |
A simple, rapid and sensitive liquid-phase microextraction was developed for the determination of polycyclic aromatic hydrocarbons (PAHs) by high performance liquid chromatography (HPLC). The studied PAHs are fluorene, phenanthrene, anthracene and fluoranthene. Deep eutectic solvent (DES) was used as an alternative green extraction solvent which was synthesized from tetrabutylammonium bromide (TBABr) and decanoic acid (DecA). The extraction procedure was performed in a commercial syringe under vortex agitation. The enriched PAHs in the DES phase was injected to HPLC and detected at 254 nm. Parameters affecting the extraction efficiency were studied and optimized. Under the optimum conditions, linearities were ranged from 10 to 500 µg L-1 and limits of detection (LODs) were in the range of 0.5−5 µg L-1. The present method was successfully applied for the analysis of trace PAHs in tea samples with satisfactory recoveries (72.8–115.5%). Moreover, the proposed method can be recognized as an excellent green analysis based on the calculated analytical Eco-Scale of 81. |
