Summary: MXene-polyvinylpyrrolidone (MXene-PVP) was prepared by physically doping and spray drying to overcome the aggregation issue of MXene. The resulting MXene-PVP was carbonized to create a carbonized MXene-PVP (MXene-PVP-C), which was then immobilized on a stainless steel wire using the sol-gel approach to produce a solid-phase microextraction (SPME) fiber. This fiber was used to extract polycyclic aromatic hydrocarbons (PAHs) from tea beverages, and the extracted PAHs were detected using gas chromatography. Central composite design methodology was employed to investigate the main SPME parameters. Under optimized conditions, the method achieved low detection limits (0.03-0.15 μg/L) and quantification limits (0.10-0.50 μg/L) for the PAHs. The method exhibited good recoveries (78.6% to 122%) for the spiked PAHs in tea beverages, with low relative standard deviations (less than 8.2% for single-fiber and 9.6% for fiber-to-fiber).

Summary: This study compared the efficiency of a self-made ZIF-8/h-BN solid-phase microextraction (SPME) fiber and commercial Tenax in predicting the bioavailability of nitrated polycyclic aromatic hydrocarbons (NPAHs) in sediments. The results showed that the NPAH concentrations reached extraction equilibrium after 72 h for the ZIF-8/h-BN fibers and after 168 h for the Tenax extraction. The SPME fiber extraction of NPAHs in sediments fitted well with the pseudo first-order kinetic model.
