Metal-organic frameworks are promising materials in diverse analytical applications especially in sample pretreatment by virtue of their diverse structure topology, tunable pore size, permanent nanoscale porosity, high surface area, and good thermostability. According to hydrostability, metal-organic frameworks are divided into moisture-sensitive and water-stable types. In the actual applications, both kinds of metal-organic frameworks are usually engineered into hybrid composites containing magnetite, silicon dioxide, graphene, or directly carbonized to metal-organic frameworks derived carbon. These metal-organic frameworks based materials show good extraction performance to environmental pollutants. This review provides a critical overview of the applications of metal-organic frameworks and their composites in sample pretreatment modes, that is, solid-phase extraction, magnetic solidphase extraction, micro-solid-phase extraction, solid-phase microextraction, and stir bar solid extraction.

“…Nowadays, researchers are focusing on fabricating composite nanofibers which exhibit specific functional properties for solid phase extraction (SPE) application [1][2][3][4][5]. Chitosan, as the second abundance of natural polysaccharide, is obtained from chitin and is well known for its biocompatible, nontoxic and biodegradable properties [6].…”

“…Development of metal organic frameworks (MOFs), which built from metal ions and organic ligands, is one of the most exciting recent developments in nanoporous material science [8]. These porous materials have unique properties such as high surface area with well-defined cavities or channels that can be used in various potential applications including gas storage, separation, drug delivery, catalysis and others [1,[9][10][11][12]. Among the tens of thousands of known MOFs, the MIL (Materials Institute Lavoisier) family, crafted from trivalent metal centers and carboxylic acid bridging ligands by Férey et al [13], has particularly attracted a great deal of attention due to its enhanced stability, very large pores and enormous porosity.…”

The nanofibers of biocompatible Chitosan/MIL-101 (Fe) composite were synthesized by a simple, cheap and accessible electrospining method and applied for mat-based extraction of trace amount of Δ9-tetrahydrocannabinol (THC) from human whole blood sample following its combination by high performance liquid chromatography-ultraviolet detection. The composite nanofibres were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, X-ray diffraction and N adsorption-desorption experiments. The volume of eluting solvent, sorbent amount, pH and% NaCl (w/v) influencing on the responses were investigated using factorial experimental design. The optimum point was achieved by analysis of the results according to design expert (DX) software. The volume of eluting solvent, sorbent amount and pH were significant variables, and 150μL, 7mg and 7.0 were respectively chosen for obtaining the best extraction response. Under the optimum conditions, the method was exhibited a linear range of 0.1-100μgL (R=0.9943) for THC with a detection limit of 0.04μgL. Acceptable values for intra-day (3.2%) and inter-day (4.8%) relative standard deviations were obtained. The high preconcentration factor (970) and satisfactory recoveries (88.2%-92.4%) in whole blood samples were achieved which proved the capability of the method for trace determination of THC in the human whole blood samples.

“…Magnetic solid-phase extraction (MSPE) is a new mode of SPE based on the magnetization of adsorbents which can be easily separated and purified during the synthesis and application process by introducing an extra magnetic field [22][23][24][25][26][27][28][29]. Magnetic core-shell MOF hybrids are rarely used in MSPE because controlling the heterogeneous growth of MOF crystals on the surface of magnetic nanoparticles remains a great challenge.…”

Core-shell metal-organic framework materials have attracted considerable attention mainly due to their enhanced or new physicochemical properties compared with their single-component counterparts. In this work, a core-shell heterostructure of CoFe2 O4 -Zeolitic Imidazolate Framework-8 (ZIF-8@CoFe2 O4 ) is successfully fabricated and used as an solid-phase extraction adsorbent to efficiently extract Congo Red and Basic Red 2 dyes from contaminated aqueous solution. Vibrating sample magnetometry indicates that the saturated magnetization of ZIF-8@CoFe2 O4 is 3.3 emu/g, which is large enough for magnetic separation. The obtained hybrid magnetic metal-organic framework based material ZIF-8@CoFe2 O4 can remove the investigated dyes very fast within 1 min of the contact time. The adsorbent ZIF-8@CoFe2 O4 also shows a good reusability. After regeneration, the adsorbent can still exhibit high removal efficiency (∼97%) toward Congo Red for five cycles of desorption-adsorption. This work reveals the great potential of core-shell ZIF-8@CoFe2 O4 sorbents for the fast separation and preconcentration of organic pollutants in aqueous solution before high-performance liquid chromatography analysis.
