Developing novel coating materials for fast and sensitive solid-phase microextraction (SPME) is highly desired but few are achieved. In this work, a new material of metal-organic framework (MOF)-derived hollow carbon nanocubes (HCNCs) was prepared as a fiber coating material for SPME. The HCNC-coated fiber (denoted as HCNCs-F) exhibited a better enrichment performance than solid carbon nanocube (SCNC)-coated fiber (denoted as SCNCs-F) and commercial fibers based on the abundant active sites of the hollow structure, hydrophobic interactions, and π-π interactions. Moreover, because of the reduced mass-transport lengths of the hollow mesoporous structure, the HCNCs-F demonstrated a faster mass transfer compared with the SCNCs-F. The HCNCs-F was used to determine the six hydrophobic polycyclic aromatic hydrocarbons (PAHs) with wide linear ranges (10-2000 ng L for naphthalene and 5-2000 ng L for the other five analytes), good reproducibility (relative standard deviation < 8.8%), and low detection limits (0.03-0.70 ng L). Finally, the HCNCs-F was successfully applied for the determination of PAHs from the real water samples. It can be concluded from the results that MOF-derived hollow carbon materials are promising candidates for the fast SPME and can be used for practical applications in analytical chemistry.

This review provides an update on the implementation of emerging materials as sorbents for sample preparation in combination with chromatographic separation. We have focused on recent applications of metal-organic frameworks, layered double hydroxides, porous carbons obtained from polymers or biomass precursors, and silicates (clays and zeolites). The review is directed toward the strategies followed by the authors to engineer suitable supports enabling the application of materials with unconventional size and shape as high-performance sorbents to explore new boundaries in sample pretreatment in manual or automated modes.

A porous material (polytriphenylamine; PTPA) was synthesized by using triphenylamine as the monomer and dimethoxymethane as the cross-linker. PTPA was characterized by Fourier infrared spectrometry, X-ray diffraction measurements, scanning electron microscopy and N adsorption-desorption isotherms. The PTPA has a spherical-shape morphology and relatively high specific surface area. It is shown to be a viable adsorbent for solid phase extraction of 3-chlorophenol, 2,3-dichlorophenol, 2,4-dichlorophenol and 2,4.6-trichlorophenol prior to their determination by high performance liquid chromatography-mass spectrometry. Under the optimized conditions, recoveries from spiked samples are in the range from 92.5% to 106.3%. The limits of detection range from 0.03 to 0.3 ng mL (at an S/N ratio of 3) in case of bottled juice, and from 0.03 to 0.1 ng g in case of tomato samples. The enrichment factors for the four analytes are in the range of 127-183 for bottle juice, and from 110-150 for tomatos. Response is linear in the range of 1.0 to 40.0 ng mL for juice, and 0.3-40.0 ng g for tomatos. The relative standard deviations for the determination of the chlorophenols at 20 ng mL in bottled beverage, and 20 ng g in tomatos are lower than 5.7%. Graphical abstract A polytriphenylamine polymer (PTPA) was prepared by using an external cross-linker method with triphenylamine as monomer and dimethoxymethane as cross-linker, and it was used as an adsorbent to extract chlorophenols from juice and vegetable samples.
