“…The LOD and LOQ for individual PAH with ranges of 0.004 to 0.026 µg/L and 0.01 to 0.07 µg/L, respectively, fell within the WFD-mandated MAC values. Structural analysis of the sorbent revealed a notable concentration of hydroxy and carboxyl groups on its surface, which are believed to enhance its affinity for PAH compounds [35]. Kouzayha and their team fine-tuned the SPE process using a C18 cartridge, with a focus on reducing the method duration.…”

“…Achieving reliable qualitative and quantitative determination of water pollutants, even in trace amounts, hinges on efficient sample preparation. The most commonly employed water sample preparation method is solid-phase extraction (SPE) [28,35,36]. In addition to various SPE techniques, this review will delve into solid-phase microextraction (SPME) [23,37,38], liquid-liquid extraction (LLE) [39][40][41], and stir-bar sorptive extraction (SBSE) [42,43] methods.…”

In the wake of rapid advancements in the pharmaceutical, food, and agricultural industries, the environment faces an increasing influx of diverse compounds, both intentionally and unintentionally released. These compounds fall into two categories: persistent and emerging pollutants. Persistent pollutants, characterized by their resistance to degradation and potential to accumulate in the environment, pose serious ecological threats. The Water Framework Directive (WFD) plays a pivotal role in monitoring and regulating these substances. This review discusses various contemporary analytical approaches to determine problematic substances, including benzo(a)pyrene, cypermethrin, dichlorvos, heptachlor, and heptachlor epoxide, aligning with the priorities outlined in the 2013 WFD classification. This review focuses on diverse water sampling methods, sample preparation techniques, and analytical methods, encompassing chromatographic, spectroscopic, and electrochemical approaches, with the primary goal of achieving the requirement laid on analytical methods used for the determination of maximum allowable concentrations defined in the WFD. Chromatographic methods, utilizing diverse mass spectrometers, have achieved detection limits as low as 10−6 μg/L, while modern electroanalytical techniques reach levels as low as 10−13 μg/L, reflecting an ongoing collective effort to enhance monitoring and safeguard the health of aquatic ecosystems. From sampling methods, large-volume sampling and passive sampling devices have been shown to be a cost-effective and modern solution, addressing limitations in traditional sampling methods, even if both of them face important pros and cons in terms of quantitative analysis.

“…SPE is a widely used technique because it can be modified to improve extraction efficiency and the enrichment factor. Efficient analyte extraction with SPE requires a suitable adsorbent material and the choice of adsorbent material depends on the target molecule and the anticipated interactions between the target analyte and the adsorbent [12,13]. Solid sorbents for the adsorption of PAHs have been fabricated using multiwalled carbon nanotubes [14], polyaniline [11], graphene [15], molecularly imprinted polymer [16], and covalent organic frameworks [17] but commercial packed-particle SPE sorbents for the extraction of PAHs normally generate high back pressure, resulting in clogging of the cartridge.…”

A hierarchical porouscomposite magnetic sorbent was fabricated and applied to the dispersive solvent‐assisted solid‐phase extraction of five polycyclic aromatic hydrocarbons. A sorbent was first prepared by incorporating graphene oxide, calcium carbonate, and magnetite nanoparticles into a polyvinyl alcohol cryogel. The graphene oxide was converted to reduced graphene oxide using ascorbic acid and a hierarchical porous structure was produced by reacting hydrochloric acid with incorporated calcium carbonate to generate carbon dioxide bubbles which created a second network. Before extracting the target analytes, the extraction solvent was introduced into the hierarchical pore network of the sorbent. The extraction was based on the partition between the analytes and introduced extraction solvent and the adsorption of analytes on reduced graphene oxide.The extraction efficiency was enhanced through π‐π and hydrophobic interactions between polycyclic aromatic hydrocarbons and reduced graphene oxide and extraction solvent. The extracted polycyclic aromatic hydrocarbons were determined by using high‐performance liquid chromatography coupled with a fluorescence detector. The developed method was applied to extract polycyclic aromatic hydrocarbons in disposable diaper, coffee, and tea samples and recoveries from 84.5 to 99.4% were achieved with relative standard deviations below 7%. The developed sorbent exhibited good reproducibility and could be reused for 10 cycles.The developed sorbent exhibited good reproducibility and could be reused for 10 cycles.The developed sorbent exhibited good reproducibility and could be reused for 10 cycles.
