“…A significant increase in the height of the peaks and, consequently, the AUC, demonstrates the efficiency of the SPME to concentrate the PAHs and provide the ability to detect and quantify them at very low concentrations. Comparing the outcome of the extraction and determination of PAHs using PPy/AC coating with the corresponding results found in the literature (6,17,(33)(34)(35) demonstrated that the developed composite coating is equivalent to or better than the ones reported earlier (Table 4).…”

“…According to the results in Table 3 , compared with the fiber SPME-HPLC-UVD [ 24 ] and SBSE-HPLC-UVD methods [ 25 ], this method achieved lower LODs, and although the linear range was not larger, it saved much more time. In the similar extraction time, the LODs were lower than that from the fiber SPME-HPLC-UVD method [ 26 ]. Furthermore, the method was online extraction and detection, which could give better repeatability than these offline methods.…”

To improve the extraction performance of the silica aerogel, a melamine-terephthalaldehyde polymer was used to hybridize silica aerogel, and the hybridized aerogel was coated on the surface of stainless steel wire to prepare a fiber-filled extraction tube through placing four wires into a polyetheretherketone tube. The tube was combined with high-performance liquid chromatography, then the online extraction and detection were established. Several polycyclic aromatic hydrocarbons (PAHs) were selected as the target analytes. Under the optimum extraction and desorption conditions, the limit of detection was as low as 3.0 ng L−1, and the linear range was 0.01–20.0 μg L−1. The enrichment factors of PAHs were in the range of 1724–2393. Three environmental water samples of mineral water, tap water and river water were analyzed by this method, and the recoveries that spiked at 1.0–10.0 μg L−1 were between 80.5–126%. It showed many advantages compared with other methods, such as better sensitivity, faster detection and online analysis.

“…Besides functionalizing, CNTs can also hybrid with organic compounds and inorganic compounds to unfold their respective properties [40][41][42][43][44][45]. In a recent study [46], CNTs were introduced within graphene to enhance the conformation of graphene and the morphology of general coating.…”

The materials used for the fabrication of solid-phase microextraction fiber coatings in the past five years are summarized in the current review, including carbon, metal-organic frameworks, covalent organic frameworks, aerogel, polymer, ionic liquids/poly (ionic liquids), metal oxides, and natural materials. The preparation approaches of different coatings, such as sol-gel technique, in-situ growth, electrodeposition, and glue methods, are briefly reviewed together with the evolution of the supporting substrates. In addition, the limitations of the current coatings and the future development directions of solid-phase microextraction are presented.
