Abstract

C18‐functionalized magnetic microspheres synthesized in a three‐stage system and characterized by Fourier transform infrared (FTIR) spectroscopy and SEM were applied for clean‐up and enrichment of polycyclic aromatic hydrocarbons (PAHs) in soil samples combined with ultrasonication extraction. Magnetic solid‐phase extraction (MSPE) parameters, such as elution solvents, amounts of sorbents, enrichment time and organic modifier, were optimized together with ultrasonication time and extraction solvents. Under the optimal conditions, the developed method provided spiked recoveries of 63.2–92.8% with RSDs of less than 6.4% and limits of detection were 0.5–1.0 ng/g. This new method provides several advantages, such as high extraction efficiency, convenient extraction procedure and short analysis times. Finally, the method was successfully applied to the determination of polycyclic aromatic hydrocarbons in soil samples.
