“…For example, Bandosz and other groups have prepared several samples of MOF/GO hybrids such as MOF-5/GO [46,47], HKUST-1/GO [48], MIL-100(Fe)/ GO [49], MIL-101(Cr)/GO [50], MOF-199/GO [51], MIL-53(Fe)/GO [52] and ZIF-8/GO [53]. The synergistic effects on porosity and chemistry of such composites result in a significant improvement in the adsorption of various gases (NH 3 , NO 2 , H 2 S, H 2 , CO 2 ) [54e61], solvents (n-hexane [62], acetone [63]) and methylene blue from wastewater [64], compared to the pristine MOFs.…”

The basic principles for the preparation of SPME fibers with satisfying selectivity, sensitivity, loading capacities and stabilities are summarized here in terms of the physicochemical properties of the coating materials and the supporting substrates of SPME fibers. While the main part of this chapter focuses on the advances in developing the most widely used coating materials, including ionic liquids, polymeric ionic liquids, carbonaceous materials, molecularly imprinted polymers, metal-organic frameworks, metals and metal oxides, conductive polymers, modified silica, as well as their composites, into SPME fibers. Meanwhile, the applications of novel SPME fibers in analyzing diverse analytes in different sample matrices are briefly reviewed, including the emerging applications of SPME in the extraction of bioactive compounds in living animals and plants.Keywords SPME fiber coating Á Ionic liquid Á Polymeric ionic liquid Á Graphene Á Carbon nanotube Á Molecularly imprinted polymer Á Metal-organic framework Á Metal and metal oxide Á Conductive polymer Á Modified silica IntroductionThe outstanding features of solid-phase microextraction (SPME), including rapid and simple operating procedures, slight disturbance to investigated systems, reduced consumption of solvents, and feasibility of automation, continuously inspire new explorations of SPME in various frontiers, such as metabolome detection [1], central nervous systems studies [2], pharmacokinetic studies [3], environmental analysis [4], and food analysis [5]. On the other hand, the diversity of the physicochemical properties of the target analytes and the complicity of the sample matrices require the development of new SPME devices to nourish the new

“…Zhang et al [11] reported that a composite of MOF-199 and carbon nanotubes possesses improved moisture resistance because it adsorbs less water in its hydrophobic pores. Similarly, another modified MOF-5 was synthesized and its potential application was explored by determination of eight organochlorine pesticides using headspace solid-phase microextraction [12]. Although these modifications improved the moisture resistance of MOFs, they cannot make the MOFs be water resistant.…”

The determination of antibiotics in biological samples is compromised by their interaction with proteins. It is showed here that the water resistant zeolite imidazolate framework 67 (ZIF-67) represents a useful sorbent for solid-phase extraction (SPE) of fluoroquinolones (FQs) from biological samples. ZIF-67 is unique in possessing permanent nanoscale porosity and a high surface area. As a result, it efficiently excludes proteins from the inner network but can well adsorb small organic molecules. Its extraction capacity for FQs exceeds that of isostructural ZIF-8, probably due to high affinity for Co(II) ions in ZIF-67. The findings were exploited to design a method for the analysis of FQs, which were extracted from bio-samples by ZIF-67 via SPE. Following elution of the absorbed FQs with NaOH/methanol, they were quantified by HPLC with diode array detection. The assay has a wide linear range that extends from 3.9 to 4000 μg⋅kg‾ 1 , with detection limits between 1.2 and 2.9 μg⋅kg‾ 1 . The method was successfully applied to the determination of FQs in manure.
