“…Subsequently, atmospheric deposition should be the major process by which PAHs may enter ecosystems and accumulate in food chains . These compounds are generally extracted from water samples either by liquid–liquid extraction , liquid–liquid microextraction (LLME) , or by SPE . In the last years new extraction techniques have been approached such as solid‐phase microextraction , stir bar sorptive extraction , and liquid‐phase microextraction .…”

Liquid-liquid microextraction coupled to LC with fluorescence detection for the determination of Environmental Protection Agency's 16 priority pollutant polycyclic aromatic hydrocarbons in rainwater has been developed. The optimization of the extraction method has involved several parameters, including the comparison between an ultrasonic bath and a magnetic stirrer as extractant apparatus, the choice of the extractant solvent, and the optimization of the extraction time. Liquid-liquid microextraction gave good results in terms of recoveries (from 73.6 to 102.8% in rainwater) and repeatability, with a very simple procedure and low solvent consumption. The reported chromatographic method uses a Core-Shell technology column, with particle size <3 μm instead of classical 5-μm particles column. The resulting backpressure was below 300 bar, allowing the use of a conventional HPLC system rather than the more expensive ultrahigh performance LC (UHPLC). An average decrease of 59% in run time and 75% in eluent consumption has been obtained, compared to classical HPLC methods, keeping good separation, sensitivity, and repeatability. The proposed conditions were successfully applied to the determinations of polycyclic aromatic hydrocarbons in genuine rainwater samples.

“…The comparison of different methods for determination of PAHs in water is shown in Table 3 . LLE [ 34 ] used less extraction time and exhibited low LOQ, but it was relatively solvent-consuming and had lower extraction efficiency. The SPE [ 35 ] method gave higher extraction efficiency.…”

In this paper, a new method of annular platform-supported headspace liquid-phase microextraction (LPME) was designed using ionic liquid as an extraction solvent, wherein extraction stability and efficiency were improved by adding an annular platform inside the extraction bottle. The ionic liquid 1-silicyl-3-benzylimidazolehexafluorophosphate was first synthesized and proved to be an excellent extraction solvent. Coupled with liquid chromatography, the proposed method was employed to analysis of polycyclic aromatic hydrocarbons (PAHs) in water and optimized in aspects of extraction temperature, extraction solvent volume, extraction time, pH, stirring rate, and salt effect of solution. The results indicated that this method showed good linearity (R2 > 0.995) within 0.5 µg·L−1 to 1000 µg·L−1 for PAHs. The method was more suitable for extraction of volatile PAHs, with recoveries from 65.0% to 102% and quantification limits from 0.01 to 0.05 µg·L−1. It has been successfully applied for detection of PAHs in seawater samples.

“…Hence, to attain the requisite accuracy and sensitivity for the experimental analysis, the preconcentration and purification steps within the pretreatment procedure were of paramount significance. Although these conventional pre-treatment methods (such as liquid-liquid extraction (LLE) (Pensado L, et al 2004)0, Gel Permeation Chromatography (GPC) (Wang J H, Guo C. 2010;Fromberg A, et al 2007;Jiang D, et al 2015), Solid-Phase Extraction (SPE) (Zheng R, et al 2014;Yin J, et al 2015;Xu T, et al 2015), QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) (Zhu J, et al 2019) can offer accuracy and detection limits, these methods often entail substantial consumption of organic solvents, time-consuming and complicated, which cannot meet the requirements of rapid, efficient and green detection under the new situation. Therefore, we currently need a simple, rapid and efficient method to detect the presence of various PAHs in oil and oilseed samples.…”

In the present research, a novel method that combines a modified dispersion solid phase extraction (d-SPE) with gas chromatography-mass spectrometry (GC-MS) analysis was developed and utilized to detect 16 different polycyclic aromatic hydrocarbons (PAHs) present in oilseed and oil samples. The modified multi-walled carbon nanotubes (NH2-MWCNTs) were prepared as d-SPE adsorbents for target analytes in the high-fat samples matrices. Compared with the traditional approach, this method can significantly shorten the pre-treatment time and reduce the use of organic solvents, making the whole process more green, environmentally friendly and sustainable practices. Several critical parameters affecting the extraction efficiency were investigated. These parameters encompassing the amount of sorbent, the type and volume of extraction solvent, desorption solution, and the time of extraction and desorption stage. Under optimal conditions, the method was validated extracting within the range of 1-200 µg/kg, and showed satisfactory linearity (R2 ≥ 0.99), acceptable recovery (70.08–104.6%) and precision (0.59–9.22%). The limits of detection were in the range of 0.04–0.42 µg/kg for all analytes. These results consistently indicate the suitability of this approach for detecting diverse PAHs in actual complex sample with the high-fat matrices.
