“…Figure 3 shows the formation pathway of highly ordered mesoporous silica using the liquid crystal templating procedure. Regardless of the procedure, the properties of the mesoporous material can be tuned by modifying the synthetic parameters (pH and temperature) and the type of surfactant and additive [3,69]. Since the first ordered mesoporous silica known as MCM41 (Mobile Composition of Matter No.…”

“…However, as the direct use of MOFs as nano/microcrystals presents a number of limitations when packing in an SPE cartridge or in dSPE (since this involves centrifugation and filtration) due to their small particle size and nonspherical shape, they should be combined with different supports in order to be readily applied as SPE materials. These strategies have also been extensively used to prepare materials for other sorptive extraction techniques, such as SPME and membrane-based techniques [3,71,74]. Table 2 lists some examples of the use of MOFs in SPE, as well as those combined with different supports for the same use.…”

This review provides an overview of the most recent developments involving materials for solid-phase extraction applied to determine organic contaminants. It mainly concerns polymer-based sorbents that include high-capacity, as well as selective sorbents, inorganic-based sorbents that include those prepared using sol-gel technology along with structured porous materials based on inorganic species, and carbon nanomaterials, such as graphene and carbon nanotubes. Different types of magnetic nanoparticles coated with these materials are also reviewed. Such materials, together with their main morphological and chemical features, are described, as are some representative examples of their application as solid-phase extraction materials to extract organic compounds from different types of samples, including environmental water, biological fluids, and food.

A novel multiwalled carbon nanotube–cyclodextrin nanocomposite for solid-phase microextraction–gas chromatography–mass spectrometry determination of polycyclic aromatic hydrocarbons in snow samples

et al. 2023

View full text Add to dashboard Cite

Novel solid-phase microextraction coatings based on the use of multiwalled carbon nanotube–cyclodextrin (MWCNT-CD) nanocomposites were developed for the determination of 16-priority polycyclic aromatic hydrocarbons at ultratrace levels in snow samples. The performance of both β- and γ-CD was tested to increase the detection capabilities towards the heaviest and most lipophilic compounds, i.e., five- and six-ring PAHs. To facilitate the interactions of MWCNTs with CDs, an oxidation procedure using both HNO3 and H2O2 was applied, obtaining superior results using MWCNTs-H2O2-γ-CD fiber. Detection and quantitation limits below 0.7 and 2.3 ng/L, RSD lower than 21%, and recoveries of 88(± 2)–119.8(± 0.4)% proved the reliability of the developed method for the determination of PAHs at ultratrace levels. The complexation capability of the γ-CD was also demonstrated in solution by NMR and fluorescence spectroscopy studies and at solid state by XRD analysis. Finally, snow samples collected in the ski area of Dolomiti di Brenta were analyzed, showing a different distribution of the 16 priority PAHs, being naphthalene, phenanthrene, fluoranthene, and pyrene the only compounds detected in all the analyzed samples.
