“…The adsorbents or coating materials, affecting the sensitivity, selectivity, and repeatability of extraction process, are the key for SPME [6]. To date, diverse advanced materials have been used as sorbents for SPME, such as mesoporous materials [7][8][9], metal nanomaterials [10][11][12], graphene [13][14][15], ionic liquids [16,17], metal-organic frameworks (MOFs) [18], covalent organic frameworks (COFs) [19,20], aerogels [21], and so on. Among these materials, aerogels as new nanomaterials have received extensive attention of researchers from different fields because of attractive merits, such as three-dimensional (3D) network, high porosities (80-98%), low density (0.37-0.87 g/cm 3 ), controllable pore structures, large specific surface (1100 m 2 /g), and outstanding thermal and mechanical properties [22][23][24].…”

A facile method was introduced for preparing a biocharcoal aerogel, which was derived from pomelo peel as the only raw material. The inner spongy layer of pomelo peel was freeze-dried for maintaining three-dimensional structure and then carbonized under high temperature and oxygen-limited conditions. The morphological structure and graphitization degree of biocharcoal aerogel were characterized using a scanning electron microscope and Raman spectrum. After sifting and grinding, the biocharcoal aerogel as an adsorbent was coated onto the surface of stainless steel wires. Through placing the wires into a polyetheretherketone tube, the in-tube solid-phase microextraction device was obtained. Coupled with high-performance liquid chromatography, it exhibited good extraction performance for polycyclic aromatic hydrocarbons, then an online analytical method was established with low limits of detection (0.005-0.050 ng/mL), wide linear ranges (0.017-15 ng/mL) with superior correlation coefficients higher than 0.9990, high enrichment factors (1128-3425), and acceptable intra-and inter-day repeatabilities (relative standard deviations ≤ 6.7%, n = 3). The method was applied to detect polycyclic aromatic hydrocarbons in bottled water samples, environmental water samples, and soft drinks with satisfactory recoveries (83.3-120.9%). This research not only developed a new carbon aerogel but also evaluated its adsorption performance in sample preparation.

“…Solid‐phase microextraction (SPME) has significant advantageous over above methods , such as no or less solvent, time‐saving, high sensitivity, convenient combination with chromatographic detection, etc . The extraction performance is mainly decided by the sorbent, so the efficient materials have been developed for SPME, including ionic liquids , metal organic frameworks , covalent organic frameworks , graphene , graphitic carbon nitride , mesoporous materials , and functional nanomaterials . There are some common properties in these high‐performance coatings, such as high surface area, excellent adsorption ability and selectivity, large porousness, good durability, and chemical stability.…”

Resorcinol-formaldehyde aerogel coating was in situ prepared on the surface of basalt fibers. The aerogel coating is uniformly modified onto basalt fibers, and it is very porous according to the characterization by using scanning electron microscopy. An extraction tube was prepared for in-tube solid-phase microextraction by placing the aerogel-coated basalt fibers into a polyetheretherketone tube. To evaluate the extraction performance toward five estrogenic compounds, the tube was connected with high performance liquid chromatography, the important extraction and desorption conditions were investigated. An online analytical method for detection of estrogens was developed and presented low limits of detection (0.005-0.030 µg/L), wide linear ranges (0.017-20, 0.033-20, and 0.099-20 µg/L), good linearity (r > 0.9990), and satisfactory repeatability (relative standard deviation < 2.7%). The method was successfully applied to detect trace estrogens in real water samples (bottled pure water and bottled mineral water), satisfactory recoveries were ranged from 80 to 125% with two spiking levels of 2 and 6 µg/L.
