样品前处理技术作为分析检测复杂样品中痕量物质的重要组成部分,不仅在很大程度上通过富集目标物来提高分析方法的选择性和灵敏度,而且还可利用对大部分干扰物的消除影响测定结果的准确性和可靠性.此外,样品前处理还决定了总的分析时间.金属有机骨架(Metal-Organic Frameworks,MOFs)材料是一类由有机桥联分子(即配体)与金属离子/金属氧簇通过配位键合构筑而成的具有拓扑结构的多孔聚合物.由于具有多样化的结构形貌、可变的孔径大小、良好的可设计性、较高的孔隙率、可调节的比表面积、多元化的组分及丰富的功能基团,金属有机骨架作为吸附材料在样品前处理领域备受关注,拥有广阔的应用前景.本文对近5年(2019-2023年)来基于金属有机骨架材料作为吸附剂所构建的固相萃取、分散固相萃取、磁性固相萃取、固相微萃取等样品前处理技术在环境、食品、生物等复杂基质中的应用进行了综述.并对金属有机骨架材料制备、功能调控及其吸附效果、萃取机理等进行了探讨.最后,对金属有机骨架材料在样品前处理领域的应用前景进行了总结展望.
Research Progress of Metal-Organic Framework-Based Materials as Sorbents in Sample Pretreatment
As one important part of analytical method for detecting trace compounds in complex samples,sample pretreatment can not only improve the selectivity and sensitivity with enrichment of target analytes,but also affect accuracy and reliability by eliminating most other interferences from samples.In additional,sample pretreatment also determines total analysis time.Metal-organic frameworks(MOFs)are a type of topological porous polymers which are constructed by self-assembly of organic linkers(also named ligands)and metal ions/metal oxygen clusters through coordination bonds.Due to their several fascinating features,such as diverse structural topologies,good designability,high porosity,large specific surface area,modifiable pore size,diversified components and rich functional groups,MOFs as sorbents in sample pretreatment have received considerable attention,and are considered to have broad application prospects.In this work,the sample pretreatment techniques including solid phase extraction,dispersive solid phase extraction,magnetic solid phase extraction,and solid phase microextraction based-on MOFs as sorbent as well as their applications in environments,foods and biological samples in the past ten years are reviewed.Furthermore,the methods for preparation and functional regulation of MOFs,as well as their analytical parameters,adsorption effect and extraction mechanism are also discussed.In the last,the application prospect of metal-organic framework materials in the field of sample preparation is summarized.
