Resumen:
Metal-organic frameworks (MOFs) are crystalline, highly porous and three-dimensional ordered materials with well-defined cages and channels. They have recently been proposed as pollutants adsorbents from aqueous media, being the Zr-based MOFs, such as the MOF808,1 the most widely used family. On the other hand, chitin is the second most abundant natural polymer used in various industrial applications.2 This polymer has a simple design, low operational cost, easy handling, high efficiency and easy regeneration ability that make it an ideal mesoporous support to generate MOF@Chitin membranes for water decontamination. In the present study, nanoparticles of MOF808 have been synthesized via solvothermal method and different amounts (5, 10 and 15 wt.%) were incorporated into the gel solution chitin composites. The synthesized chitin/MOF808 composites were structurally, morphologically and thermally characterized by means of X-ray diffraction, Raman and IR spectroscopies, TEM and SEM microscopy and by thermogravimetric (TGA/DSC) analysis. The surface area of the composites was also determined by BET method and the potential for the removal of organic (dyes) and inorganic (metals) pollutants from aqueous media was investigated showing an improvement between 30% and 50% comparing with the pristine chitin or MOF material.
