摘　　要：金属有机框架(Metal-Organic Frameworks, MOFs)是一种由金属离子或团簇与有机连接基团通过配位键合成的多孔晶体材料。NH_(2)-MIL-68(In)作为一种典型的金属有机框架,因其具有高比表面积、可调孔径和功能性,在气体储存、分离、催化以及光电等领域展现出巨大的应用潜力。本研究旨在深入探讨NH_(2)-MIL-68(In)的结构特点、制备方法及其在相关领域的应用研究进展。通过运用多种实验手段,我们采用溶剂热法制备NH_(2)-MIL-68(In),经后合成修饰分别制备出NH_(2)-MIL-68(In)-AA和NH_(2)-MIL-68(In)-CMC样品,对产物结构性质和性能表现进行了系统研究。研究发现,因NH_(2)-MIL-68(In)的较高比表面积和孔容,其在诺氟沙星萃取方面有很大优势,经过不同p H对诺氟沙星萃取分析,在p H=10时,NH_(2)-MIL-68(In)-CMC和NH_(2)-MIL-68(In)-AA萃取诺氟沙星的效果最好,经过不同洗脱液对诺氟沙星的萃取实验发现,NaOH的洗脱效果最好。本研究不仅加深了对NH_(2)-MIL-68(In)及后合成产物的结构和性能理解,也为该材料在实际生产中的进一步应用提供了实验依据。Metal-Organic Frameworks(MOFs)is a kind of porous crystal material synthesized by coordination bond between metal ions or clusters and organic linking groups.NH_(2)-MIL-68(In),as a typical Metal-Organic Framework,shows great application potential in gas storage,separation,catalysis and optoelectronics due to its high specific surface area,adjustable pore size and functionality.The purpose of this study is to investigate the structural characteristics,synthesis methods and application of NH_(2)-MIL-68(In)in related fields.Through the application of various experimental methods,NH_(2)-MIL-68(In)was prepared by the solvothermal method,and then NH_(2)-MIL-68(In)-AA and NH_(2)-MIL-68(In)-CMC samples were prepared via the method of Post-Synthetic Modification.The structural properties and performance of the products were systematically studied.Research has found that NH_(2)-MIL-68(In)has significant advantages in the extraction of norfloxacin due to its high specific surface area and pore volume.After analysis of norfloxacin extraction at different pH values,NH_(2)-MIL-68(In)-CMC and NH_(2)-MIL-68(In)-AA had the best effects in norfloxacin extraction at pH=10.And NaOH was found to have the best elution effect.This study not only deepens the understanding of the structure and properties of NH_(2)-MIL-68(In)and its subsequent synthesized products,but also provides experimental basis for the further development of this material in practical applications.
