Abstract: Metal-Organic Frameworks(MOFs)is a kind of porous crystal material synthesized by coordination bond between metal ions or clusters and organic linking groups. NH2-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 NH2-MIL-68(In)in related fields. Through the application of various experimental methods, NH2-MIL-68(In)was prepared by the solvothermal method, and then NH2-MIL-68(In)-AA and NH2-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 NH2-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, NH2-MIL-68(In)-CMC and NH2-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 NH2-MIL-68(In)and its subsequent synthesized products, but also provides experimental basis for the further development of this material in practical applications.

Key words: NH2-MIL-68(In), MOFs, extraction, norfloxacin
