Metal-Organic Frameworks (MOFs) are highly porous and selective materials known as inorganic polymer structures in which metal clusters are connected by organic spacers. This new class of materials has been highlighted as adsorbent material of heavy metals and organic dyes. Contamination of water from industrial effluents containing such substances is a concern because its harmful effects on the aquatic biosphere. In this context, the objective of this project is to develop MOF films using three substrates derived from cellulose: bacterial cellulose, filter paper and cotton fabric, using ZIF-8 and MOF-808. The surface of these substrates will be funcionalizated with the propose of facilitating the fixation and nucleation of the crystals. The films will be produced by the in situ growth of the MOFs, using solvothermic and/or microwave assisted synthesis. The materials will be characterized by the techniques of infrared spectroscopy, powder X-ray diffraction, transmission electron microscopy, thermal analysis, fisistion of nitrogen, scanning electron microscopy and dispersive energy spectroscopy. Finally, the materials produced will be tested for their use as adsorbents of organic dyes and europium (III) ions and heavy metals.
