Resumen

The present study refers to the synthesis and characterization of metal-organic structures of the UiO-Zr family, these being UiO-66, UiO-66-HN2 and UiO-67. The syntheses were carried out under solvothermal conditions, while the characterization of the hybrid materials was made by thermogravimetry and x-ray diffraction. Defects in the synthesized materials was controlled by the amount of the modulator used during the synthesis. All the synthesized materials were purified prior their characterization to avoid the presence of unreacted material in the pores of the crystalline structure. It was observed that the synthesis time can affect the physical appearance of the metal organic framework (MOF), making it in a gel form, preventing it from being obtained in powder form by the process used. Since the materials obtained were meant to be applied in the sorption of organic pollutants from water, an absorbance analysis was performed for the pharmaceutical contaminant, paracetamol, in which a good fit was obtained with a value of R2 = 0.9833.

For a possible study in the future, research perspectives are included such as the development of an adsorption kinetic analysis for the design of a reactor and thus evaluate MOFs as catalysts.

Key Words. Metal-Organic Frameworks, solvothermal synthesis, Surface modification, thermogravimetric analysis, X-RAY diffraction analysis.
