“…And Luo et al [85] prepared another substrateless graphene fiber by hydrothermal reduction of graphene oxide in a capillary mold. In addition, GO, functionalized graphene, and the composites of graphene were also developed into SPME fiber coatings by using the similar methods aforementioned [86][87][88][89][90].…”

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].

Graphene is a new carbon-based material that is of interest in separation science. Graphene has extraordinary properties including nano size, high surface area, thermal and chemical stability, and excellent adsorption affinity to pollutants. Its adsorption mechanisms are through non-covalent interactions (π-π stacking, electrostatic interactions, and H-bonding) for organic compounds and covalent interactions for metal ions. These properties have led to graphene-based material becoming a desirable adsorbent in a popular sample preparation technique known as solid phase extraction (SPE). Numerous studies have been published on graphene applications in recent years, but few review papers have focused on its applications in analytical chemistry. This article focuses on recent preconcentration of trace elements, organic compounds, and biological species using SPE-based graphene, graphene oxide, and their modified forms. Solid phase microextraction and micro SPE (µSPE) methods based on graphene are discussed.

“…For headspace SPME, the volume ratio of the sample solution to headspace is another important parameter impacting the mass distribution equilibrium [35]. The effect of sample volume was investigated through the experiment by changing the water volumes from 6.0 to 16.0 mL with the extraction being performed in a 20.0 mL glass vials at the same concentrations of the analytes in the water samples.…”
