“…This means that sample pre-treatment is required, with the aim of concentrating the PAHs, as well as eliminating or decreasing interference [30]. For the isolation of PAHs in environmental matrices, various sample pre-treatment techniques have been proposed, including solid-phase extraction (SPE) [31,32], liquid-liquid extraction (LLE) [33], miniaturized homogeneous liquid-liquid extraction (MHLLE) [34], solid-phase microextraction (SPME) [35,36] and single drop microextraction (SDME) [37,38]. Although these techniques are very useful, they possess some serious drawbacks.…”

Fabric phase sorptive extraction (FPSE) combines the advanced material properties of sol-gel derived microextraction sorbents and the flexibility and permeability of fabric to create a robust, simple and green sample preparation device. It simultaneously improves the extraction sensitivity and the speed of the extraction by incorporating high volumes of sponge-like, porous sol-gel hybrid inorganic-organic sorbents into permeable fabric substrates that are capable of extracting target analytes directly from both simple and complex aqueous sample matrices. For the first time, this technique was applied to the trace-level determination of selected polycyclic aromatic hydrocarbons (PAHs) in environmental water samples using a non-polar sol-gel C18 coated FPSE media. Several extraction parameters were optimized to improve the extraction efficiency and to achieve a high detection sensitivity. Validation tests of spiked samples showed good linearity for four selected PAHs (R 2 = 0.9983-0.9997) over a wide range of concentrations (0.010-10 ng/mL). Limits of detection (LODs) and quantification (LOQs) were measured at pg/mL levels; 0.1-1 pg/mL and 0.3-3 pg/mL, respectively. Inter-and intra-day precision tests showed variations of 1.1%-4.1% for four selected PAHs. Average absolute recovery values were in the range of 88.1%-90.5% with relative standard deviations below 5%, surpassing the values predicted by the recovery prediction model. Finally, the developed FPSE-HPLC-FLD protocol was applied to analyze 8 environmental water samples. Out of four selected PAHs, fluoranthene (Flu) and phenanthrene (Phen) were the most frequently detected in four samples, at concentrations of 5.6-7.7 ng/mL and 4.1-11 ng/mL, respectively, followed by anthracene (Anth) and pyrene (Pyr) in two samples. The newly developed FPSE-HPLC-FLD protocol is simple, green, fast and economical, with adequate sensitivity for trace levels of four selected PAHs and seems to be promising for routine monitoring of water quality and safety.

“…Compared with more commonly used ILs containing the [PF 6 ] anion, the [FAP]-containing ILs resulted in increased EFs (13-29%) for the extraction of PAHs. The same authors also reported the use of two water-miscible micellar IL solvents for the HS-SDME of 17 aromatic compounds from aqueous solutions [68]. Two different surfactants, namely, sodium dodecyl sulfate (SDS) and [C 10 C 1 IM][Br], were directly dissolved in [C 4 C 1 IM][Cl] at 2.5 times the critical micelle concentration and used as extractant phases.…”

The present article offers a glance at achievements in single-drop microextraction(SDME), with a focus on the two most commonly used modes of this technique: headspace and direct immersion. Factors affecting SDME, such as the pH and ionic strength of the sample solution, the stirring rate, and the extraction time are briefly summarized. The requirements for the acceptor phase and the influence of the sampling temperature are presented. In addition, the potential of the application of microwave and ultrasonic energy in SDME is also discussed. Examples of the application of the headspace and direct immersion modes of SDME are given in a table as additional Supporting Information.
