Special Issue Information

Dear Colleagues,

Sample preparation plays a vital role prior to qualitative and quantitative analysis of trace analytes in complicated matrix samples. Nowadays, the extraction performance of sample preparation techniques, including solid-phase extraction (SPE), micro-solid-phase extraction (μ-SPE), dispersive solid-phase extraction (DSPE), solid-phase microextraction (SPME), stir bar sorptive microextraction (SBSME), thin-film microextraction (TFME), and others, largely depends on the properties of the sorbents. Nanoporous polymer-based composites and their derivatives present outstanding adsorption capacities when capturing targeted compounds owing to their large specific areas, high porosities, and tunable chemical structures. Therefore, various nanoporous composites based on polymers and their derivatives have been developed as sorbents and extensively applied in food, environmental, pharmaceutical, and biological analysis during the past years. Nevertheless, novel nanoporous composites need to be further explored to improve the extraction capacities and selectivity of analytes from complex samples. Herein, studies on the preparation of novel nanoporous polymer-based composites and their derivatives used as sorbents for sample preparation are of interest for this Special Issue. In addition, studies on pollutant removal from environmental matrices based on advanced nanoporous composites are also invited.

Herein, novel, loose, and porous graphite phase carbon nitride/porous carbon (g-C3N4@PC) composites were prepared by decorating cellulose nanocrystals (CNCs). The characterization results demonstrate that the as-prepared composites presented high specific surface areas, porous structures, and abundant chemical groups, with the modification of CNCs. In view of the unique advantages, g-C3N4@PC was used as the coating material for the solid-phase microextraction (SPME) of organochlorine pesticides (OCPs) in water and juice samples. The g-C3N4@PC-coated fibers showed better extraction efficiencies than commercial fibers (100/7 μm PDMS and PA) toward the OCPs, with the enrichment factors of the g-C3N4@PC-coated fibers 5–30 times higher than the latter. Using a gas chromatography–mass spectrometry (GC-MS) instrument, the g-C3N4@PC-coated fibers exhibited a gratifying analytical performance for determining low concentrations of OCPs, with a wide linear range (0.1–1600 ng L−1 for water; 0.1–1000 ng L−1 for juice), low limits of detection (0.0141–0.0942 ng L−1 for water; 0.0245–0.0777 ng L−1 for juice), and good reproducibility and repeatability in optimal conditions. The established method showed good sensitivity and recovery in the determination of OCPs in the water and fruit juice samples, which displayed broad prospects for analyzing organic pollutants from environmental samples.
