Metal-organic frameworks have a unique porous structure and have great potential in solid-phase microextraction. Solid-phase microextraction coatings based on metal-organic frameworks have high surface area, selectivity, stability, and extraction efficiency. Although there have been many studies on the synthesis of such fibers, commercial availability is still limited. This article reviews the applications of metal-organic framework-based solid-phase microextraction coatings in the measurement of volatile organic compounds, polycyclic aromatic hydrocarbons, persistent organic pollutants, phenols, and polychlorinated biphenyls, and discusses the technical challenges and future potential.
Metal-organic frameworks have drawn increasing attention in the field of solid-phase microextraction due to their unique porous structure. Solid-phase microextraction coatings based on metal-organic frameworks exhibit large surface area (up to 1458 m2/g), high selectivity, stability (up to 270 extraction/desorption cycles), and extraction efficiency. Although there have been numerous studies on the synthesis of such fibers, many are not commercially available. In situ deposition from solution, chemical vapor deposition, electrodeposition, adhesion, sol-gel, and chemical bonding techniques are discussed among the methods reported to prepare coatings based on a metal-organic framework. Applications of these coatings for the measurement of volatile organic compounds, polycyclic aromatic hydrocarbons, persistent organic pollutants, phenols, and polychlorinated biphenyls are reviewed and critically discussed. The concluding remarks outline technical challenges and future potential of metal-organic framework based solid-phase microextraction fibers.
