“…Ultrasonic liquid extraction under optimized conditions provides chromatographic determination limits of PAHs at a level of 2 μg/L for water bodies [52] or 0.002 μg/kg for soils and bottom sediments [53]. The high efficiency of ultrasonic emulsion liquid-liquid extraction in the recovery of 16 PAHs from an aqueous medium in combination with a high degree of preconcentration [54] made it possible to reach determination limits of 0.5 ng/L in the GC-MS analysis for PAHs containing three or four benzene rings.…”

The review systematizes data on various extraction techniques for sample preparation in the determination of polycyclic aromatic hydrocarbons (PAHs) in environmental samples, provides a classification, and describes the capabilities of these techniques. The main versions and methods of solid-phase extraction (SPE) and liquid-liquid (LLE) extraction of structurally different PAHs from complex multicomponent systems are discussed. The variety of SPE and LLE methods, the peculiarities of their combinations with other methods, and the advantages and disadvantages of each sample preparation method are demonstrated. Chromatographic methods are preferred for detection after the solid-phase or liquid-liquid extraction of PAHs from environmental samples.

“…Combining these methods with ultrasound treatment accelerates mass transfer and consequently increases effectiveness of the processes [ 17 ]. A procedure consisting of ultrasound-assisted LLE with n -hexane and GC-MS detection has been suggested by us for the extraction and quantification of PAHs from different types of water samples [ 18 ]. The procedure provided high recoveries (90%) of PAHs; however, this method is time- and labor-consuming and has high organic solvent consumption.…”

Polycyclic aromatic hydrocarbons (PAHs) are a class of persistent organic pollutants of water, and their determination at trace levels in the aquatic ecosystems is essential. In this work, an ultrasound-assisted dispersive liquid–liquid microextraction (DLLME) procedure was suggested utilizing a binary dispersive agent for recovery of different molecular weight polycyclic aromatic hydrocarbons (PAHs) from waters. The detection was carried out by gas chromatography–mass spectrometry (GC-MS) as well as high-performance liquid chromatography with fluorescence and diode-array detection (HPLC-FD/PDA). The method was optimized for the extraction of analytes with respect to the mixture composition, ratios of components, ultrasonication time and centrifugation parameters. The analytical schemes for PAHs extraction from water samples using different ratios of extraction and dispersive solvents are reported. The mixture consisting of chloroform and methanol was applied for the extraction of PAHs containing two or three fused aromatic rings; the mixture of chloroform and acetonitrile is suitable for PAHs containing more than four aromatic rings. The mixture of chloroform:acetone + acetonitrile was applied in the universal scheme and allowed for the simultaneous extraction of 20 PAHs with different structures. The developed sample preparation schemes were combined with GC-MS and HPLC-FD/PDA, which allowed us to determine the analytes at low concentrations (from 0.0002 µg/L) with the recoveries exceeding 80% and relative standard deviations of about 8%. The developed methods for the determination of 20 PAHs were applied to the analysis of water samples from the Karasun Lake (Krasnodar), Azov Sea (Temryuk) and Black Sea (Sochi).
