Metal-organic frameworks are a family of porous coordination polymers made of suitable metal units and organic groups. These compounds not only have a large number of suitable topologies, but they also perform many applications including gas storage, heterogeneous catalysis, sensing, drug delivery, and separation. Among the structures used for this purpose are the metal-organic frames of the columnar layers in which the columns play an important role in the properties of the framework. Using different columns, different properties can be created in these structures.
TMU-22 and similar structures are one of these frameworks that show good stability in aquatic environments and considering that the uptake of pollutants from aquatic environments is a problem for us and It is also a challenge, and because of our ability to easily change columns for different applications, these structures and compounds are similar to different columns for adsorption processes. TMU-22 was characterized using infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermal gravimetric analysis (TGA). By using the adsorption technique, the adsorption capacity of this compound was investigated and with the results obtained from the adsorption isotherms, the maximum adsorption capacity for paranitrophenol, aniline and paraanisidine species is 109.09, 166.66 and 98 mg / g, respectively. Also, among polluting species, this adsorbent has a higher tendency to absorb aniline than other species.
