金属-有机骨架材料具有结构多样、孔径大小可调、永久性纳米孔隙率、高比表面积和良好的热稳定性等优点，在分析领域有着广阔的应用前景。根据水稳定性，金属有机骨架材料分为湿敏型和水稳定型。在实际应用中，这两种金属有机骨架通常被设计成含有磁铁矿、二氧化硅、石墨烯的杂化复合材料，或者直接被修饰到金属有机骨架衍生的碳上。这些金属有机骨架材料对环境污染物表现出良好的萃取性能。本文综述了金属有机骨架及其复合材料在固相萃取、磁固相萃取、微固相萃取、固相微萃取和搅拌棒固相萃取等样品前处理模式中的应用。
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 solid-phase extraction, micro-solid-phase extraction, solid-phase microextraction, and stir bar solid extraction.
