“…MSPE overcomes the limitations of traditional SPE methods, such as back pressure in cartridges and time-consuming processes that slow down the analysis. The use of magnetic adsorbents enables immediate separation of extracts and adsorbents without the need for centrifugation or filtration [10][11][12][13]. The choice of a suitable sorbent is crucial in the MSPE method [14,15].…”

To address sustainability issues, the green synthesis of nanomaterials has recently received considerable attention. This article addresses a novel and cost‐effective adsorbent for the extraction of eight phenyl‐N‐methylcarbamate insecticides from water samples. We first synthesized a magnetite/hydroxyapatite nanocomposite using snail shell powder via an environmental friendly approach. The morphology and physicochemical properties of magnetic hydroxyapatite were characterized by Fourier transform infrared spectroscopy, energy‐dispersive X‐ray spectroscopy, and scanning electron microscopy. Magnetic extraction parameters were optimized using a Doehlert matrix. Under optimum conditions, the magnetic extraction coupled with a LC–MS method shows good linearity with R2 ≥ 0.9982, suitable intra‐ and interday precision, and limits of detection and quantification in the range of 0.052–0.093 μg/L and 0.11–0.31 μg/L, respectively. Satisfactory relative recoveries of all carbamates were achieved from fortified water samples in the range of 93.89–101.01%.

“…22 MOF dispersive forces are raised when combined with other substrates such as MNPs (Fe 3 O 4 ) and nanomaterials composed of carbon such as graphene (G), 23 carbon nanotubes (CNTs), 24 and carbon nanofibers (CNFs), which influence the aggregation, morphology, structure, and size. 25,26 Also, the modification of CNFs with MOF structures can enhance thermal and chemical stability, porosity, surface area, and adsorption properties. 26,27 Based on the description provided above, magnetic CNF was modified with MIL-101(Cr) (Fe 3 O 4 @CNF@MIL-101) and used as a sorbent in real water samples for the MSPE of PAHs.…”
