“…This method was introduced in 1990 to overcome the major drawbacks of conventional SPE, including complexity in automation and instrument design [ 17 ]. This method eliminates the need for organic solvents and significantly shortens the analysis time [ 18 ]. SPME has gained wide attention due to its advantages, such as high sensitivity, solvent-free methods, and simplicity of operation.…”

In recent years, the utilization of biomass materials for the removal and detection of water pollutants has garnered considerable attention. This study introduces, for the first time, the preparation of Fe3O4/persimmon leaf magnetic biomass composites. The magnetic composites were employed in a magnetic solid-phase extraction method, coupled with gas chromatography-electron capture detection (GC-ECD), for the analysis of four pesticides (trifluralin, triadimefon, permethrin, and fenvalerate) in environmental water samples. The innovative magnetic persimmon leaf composites were synthesized by in situ generation of Fe3O4 nanoparticles through coprecipitation and loaded onto persimmon leaves. These composites exhibit superparamagnetism with a saturation magnetization of 12.8 emu g−1, facilitating rapid phase separation using a magnetic field and reducing the extraction time to 10 min. Desorption can be achieved within 30 s by aspirating 20 times, eliminating the need for time-consuming and labor-intensive experimental steps like filtration and centrifugation. The specific surface area of the magnetic composite adsorbent increased from 1.3279 m2 g−1 for the original persimmon leaf to 5.4688 m2 g−1. The abundant hydroxyl and carboxyl groups on the composites provide ample adsorption sites, resulting in adsorption capacities ranging from 55.056 mg g−1 to 73.095 mg g−1 for the studied pesticides. The composites exhibited extraction recoveries ranging from 80% to 90% for the studied pesticides. Compared to certain previously reported MSPE methods, this approach achieves equivalent or higher extraction recoveries in a shorter operation time, demonstrating enhanced efficiency and convenience. Good linearity of the target analytes was obtained within the range of 0.75–1500 μg L−1, with a determination of coefficient (R2) greater than 0.999. These findings contribute to the use of magnetic persimmon leaf biomass materials as effective and environmentally friendly adsorbents for pollutant determination in water samples.

“…The SPE method is widely in demand due to the possibility of its modification, for example, using coordination polymers (CPs) capable of interacting with antibiotics and forming supramolecular complexes, about which not much is known, and which are capable of luminescence under certain conditions [19]. In addition, the SPE method can be easily automated for fast and on-line analyses since it can be combined with gas or liquid chromatography, photoluminescence [19] and other analytical methods [19,20]. SPE is widely in demand due to the possibility of its automation and ease of combination with gas and liquid chromatography, as well as other analytical methods [20].…”

The coordination polymer was obtained based on cobalt trimesinate. It was characterized by elemental analysis, IR spectroscopy, X-ray diffraction analysis and scanning electron microscopy. The polymer was studied as a sorbent for solid-phase extraction of tetracycline antibiotics. Cobalt trimesinate had a high adsorption capacity (400 mg/g). Antibiotic adsorption followed the pseudo-second-order kinetic model and the Freundlich isotherm model. The process proceeded spontaneously, as indicated by the calculated thermodynamic parameters. The resulting coordination polymer has good stability and recyclability. The possibility of using cobalt trimesinate for the determination of tetracycline in various milk samples was investigated. This work holds great promise for the development and application of a cobalt trimesinate-based coordination polymer for use in sample preparation to replace the time-consuming vacuum evaporation procedure with a relatively simple solid-phase extraction procedure.

“…Over the years, a number of sample preparation methods have been developed, such as liquid–liquid extraction (LLE) ( Hammad et al, 2021 ), solid-phase extraction (SPE) ( Fedotov et al, 2019 ), and dispersive solid-phase extraction (DSPE) ( Khashaba et al, 2021 ; Salehpour et al, 2021 ) as well as microextraction techniques including dispersive liquid–liquid microextraction (DLLME) ( Rezaee et al, 2006 ; Zuloaga et al, 2015 ; Mansour and Khairy, 2017 ; Wu et al, 2019 ), solid-phase microextraction (SPME) ( Hawthorne et al, 1992 ; Duman et al, 2020 ; Jagirani and Soylak, 2020 ), and single-drop microextraction (SDME) ( Liu and Dasgupta, 1996 ; Choi et al, 2011 ; Delove Tegladza et al, 2020 ). DLLME is one of the most efficient methods for the separation and preconcentration of analytes due to its ease of operation and low cost ( Moslemzadeh et al, 2020 ).…”

Synergistic Combination of Facile Thiol-Maleimide Derivatization and Supramolecular Solvent-Based Microextraction for UHPLC–HRMS Analysis of Glutathione in Biofluids

et al. 2021

Glutathione (GSH) is the most abundant non-protein thiol in biofluids, enabling diverse physiological functions. Among the proposed methods for GSH detection, ultra-high-performance liquid chromatography (UHPLC) coupled with high-resolution mass spectrometry (HRMS) has the advantages of high sensitivity and efficiency. In this study, a novel analytical method was developed for the determination of GSH using supramolecular solvent (SUPRAS)-based dispersive liquid–liquid microextraction (DLLME) and UHPLC–HRMS. N-Laurylmaleimide was dissolved in tetrahydrofuran, which served three functions: 1) precipitate the proteins present in the biofluid sample, 2) provide a reaction environment for derivatization, and 3) enable the use of SUPRAS as the dispersing agent. Critical parameters were optimized based on single factor testing and response surface methodology. The established method was validated in terms of linearity, accuracy, precision, and successful quantitative analysis of GSH in saliva, urine, and plasma samples. Experimental results showed that SUPRAS as an extraction solvent was particularly suitable for the extraction of GSH from complex matrices. The current study provides a useful tool for accurate measurements of GSH concentrations, which could potentially be used for clinical diagnostics.
