Sample pretreatment is an important prerequisite for analyzing complex samples due to the low concentration of targets and numerous interferences in sample matrix. As a group of emerging absorbents, metal-organic frameworks (MOFs)-derived porous carbons (MPCs), obtained by high-temperature pyrolysis of MOFs, have been brought into stage recently due to their intrinsic advantages such as high porosity, permanent nanoscale cavities and open channels. The morphology of the original MOF precursor is well maintained after calcination produces. Furthermore, by directly calcinating MOFs comprised of magnetic metal centers (Co, Fe, Ni), magnetic porous carbon with excellent magnetism and separation efficiency can be fabricated. The uniformly distributed magnetic metal nanoparticles in the carbon matrix is helpful to reduce the agglomeration problem of magnetic nanoparticles and the porosity of carbon materials inherited from MOFs is beneficial to evaluate the adsorptive property. So MPCs has been widely used in sample preparation of environmental, biological samples and food matrices. In this review, we summarize the performances and different process for the preparation of MPCs. Moreover, this review mainly focuses on providing a detailed discussion about the application of MPCs for extracting analytes from complex matrix in different sample pretreatment modes such as solid-phase extraction, magnetic solid phase extraction and solid-phase microextraction. In addition, the efforts recently on the automation of magnetic solid phase extraction processes by means of MPCs are also described.

样品预处理是分析复杂样品的重要先决条件，因为目标物的浓度低且样品基质中存在大量干扰。作为一组新兴的吸收剂，通过MOF的高温热解获得的衍生自金属有机骨架（MOF）的多孔碳（MPC）由于其固有的优势（例如高孔隙率，永久的纳米级空腔）而已于近期投入使用。和开放渠道。煅烧产生后，原始MOF前体的形态得到了很好的维持。此外，通过直接煅烧由磁性金属中心（Co，Fe，Ni）组成的MOF，可以制造具有优异的磁性和分离效率的磁性多孔碳。碳基体中均匀分布的磁性金属纳米颗粒有助于减少磁性纳米颗粒的团聚问题，而从MOF继承的碳材料的孔隙率则有助于评估吸附性能。因此，MPC已广泛用于环境，生物样品和食品基质的样品制备中。在这篇综述中，我们总结了制备MPC的性能和不同过程。此外，本文的主要重点是提供有关MPC在固相萃取，磁性固相萃取和固相微萃取等不同样品预处理模式下从复杂基质中萃取分析物的应用的详细讨论。此外，
