MOFs (metal-organic frameworks) is a kind of material centered by the organic ligand and metal forms through self-assembly with adjustable aperture.Compared with traditional inorganic porous materials, MOFs has larger specific surface area, higher porosity, and the structure and function are more diverse.This paper introduces the application research progress of the MOFs materials in modern sample pre-treatment technology, focuses on application research of MOFs in solid phase extraction, solid phase micro extraction, magnetic solid phase extraction and stir bar sorptive extraction.%金属-有机骨架(metal-organic frameworks,MOFs)材料是一类由金属中心与有机配体经过自组装形成的具有可调节孔径的材料.与传统的无机多孔材料相比,MOFs材料具有更大的比表面积,更高的孔隙率,结构及功能更加多样.综述了MOFs材料在现代样品前处理技术中的应用,重点总结其在固相萃取、固相微萃取、磁固相萃取、搅拌棒吸附萃取中的应用研究进展.
