“…The core component for SPME is the coating material. To date, various SPME coatings, including metal oxide nanoparticles, graphene, polymeric ionic liquids, metal–organic frameworks (MOFs), and covalent organic frameworks (COFs), have been applied for the determination of PCBs. − Among them, COFs have significantly emerged as promising tracking platforms. COFs possess inherent advantages of permanent porosity and well-defined pore structure as well as superior stability.…”

Polychlorinated biphenyls (PCBs) are persistent organic pollutants that pose a severe threat to the environment and organisms, even at trace levels. In this study, we used carboxylated covalent organic frameworks (COFs) as molecular probes for the extraction of trace PCBs using solid-phase microextraction (SPME). Benefiting from the flexible and adjustable features of the COFs, a series of carboxylated COFs with different pore sizes were tailored and fabricated as SPME fibers. The carboxylated COFs presented significant extraction sensitivity and specificity compared to the pristine COFs, which were attributed to the interplay of twisted nanochannels and formed secondary nanopores, as well as the intermolecular hydrogen bonding between COFs and PCBs. The limits of detection (LODs) were calculated to be 0.02−0.2 ng L −1 , which were much lower than the maximum content of PCBs in drinking water recommended by the United States Environmental Protection Agency (USEPA) (0.5 μg L −1 ). Furthermore, SPME probes were successfully performed for PCB detection in real water samples with satisfactory results. This study demonstrated the potential of carboxylated COF-based SPME fibers for the selective extraction of PCBs and could contribute to the development of new and effective SPME coatings for the efficient detection of pollutants in environmental samples efficiently.

“…Thus, substances that fully comply with these requirements are, no doubt, ionic liquids. Furthermore, ILs have the possibility of being combined from different cation and anion pairs, allowing them to obtain the demanded properties, thus allowing them to be called designer solvents [ 19 , 20 ].…”

This work demonstrates the suitability of a newly developed ionic liquid (IL)-based silica SPME fiber for the determination of seven organophosphorus insecticides in cucumber and grapefruit samples by headspace solid-phase microextraction (HS-SPME) with a gas chromatography–flame ionization detector (FID). The sol-gel method released four different sorbent coatings, which were obtained based on a silica matrix containing ILs immobilized inside its pores. In order to obtain ionogel fibers, the following ionic liquids were utilized: 1-Butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide; Butyltriethyl ammonium bis(trifluoromethylsulfonyl)imide; 1-(2-Methoxyethyl)-3-methylimidazolium bis(trifluoromethylsulfonyl)imide, and 1-Benzyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide. The developed fibers were applied for the extraction of seven different insecticides from liquid samples. The most important extraction parameters of HS-SPME coupled with the GC-FID method were optimized with a central composite design. The new SPME fiber demonstrated higher selectivity for extracting the analyzed insecticides compared with commercially available fibers. The limit of detection was in the range of 0.01–0.93 μg L−1, the coefficients of determination were >0.9830, and 4.8–10.1% repeatability of the method was found. Finally, the obtained ionogel fibers were utilized to determine insecticides in fresh cucumber and grapefruit juices.

“…Moreover, the prepared SPME devices can be further assisted by other extra energies, such as electricity and magnetism, realizing fast mass transfer. − It can be seen that the coating material, coating fabrication method, and extraction device design are three key aspects for the enhanced extraction performance of SPME, and these are constantly being innovated. Finally, these fabricated SPME devices can be combined with diverse instruments to develop analytical methods for the precise quantification of trace target analytes or identification of biomarkers from abundant untargeted analytes …”
