金属-有机骨架材料(Metal-organic frameworks,MOFs)具有超大的比表面积和孔容积、可调的孔径和拓扑结构、良好的热稳定性等优点,因而被广泛用于气体储存、催化、吸附和分离等领域。近年来,以MOFs为吸附剂的样品预处理研究已引起广泛关注。本文综述了近7年来MOFs应用于样品预处理,如采样、固相萃取和固相微萃取等的研究进展,并对这一领域进行了展望。
Due to the unique properties such as diverse structure topology,tunable pore size,permanent nanoscale porosity,high surface area,good thermostability and uniform structured cavities,metal-organic frameworks(MOFs) are widely used for hydrogen storage,catalysis,adsorption and separation.Recently,MOFs have shown great potential for sample pretreatment.This review summarizes the recent advances in the application of MOFs for sample pretreatment,such as sample collection,solid-phase extraction,and solid-phase microextraction.The prospects of MOFs for sample pretreatment are also presented.
