Nanocomposite fiber analysis and their interactions with salts in aqueous solution Hurtado García, Violeta Rodríguez Pérez, Miguel Ángel Barroso Solares, Suset The high concentration of nitrates in aquifers, rivers and open waters mainly due to the industrial use of fertilizers is one of the main ecological problems facing society today. In this work, nanocomposite fibers doped with modified sepiolite have been developed for nitrate adsorption. Their adsorption capacity (q) has been tested, reaching the value of q ∼ 20 mg/g in an exposure time of 1 minute. This is an improvement on materials dedicated to water decontamination in this field, which reach similar capacities but in contact times between 24 and 72 hours. The nanocomposite fibers produced were foamed by gas dissolution and a characterization work has been carried out on both solid and foamed fibers by electron microscopy (SEM), thermogravimetry (TGA), differential scanning calorimetry (DSC) and atomic force microscopy (AFM). Furthermore, mechanical properties of the fibers in the AM-AFM mode have been tested. 2023 info:eu-repo/semantics/masterThesis eng Departamento de Física de la Materia Condensada, Cristalografía y Mineralogía Departamento de Química Física y Química Inorgánica https://uvadoc.uva.es/handle/10324/63636 https://uvadoc.uva.es/bitstream/10324/63636/3/license.txt 289d98c1665ee0d20312360f0e8643c8 https://uvadoc.uva.es/bitstream/10324/63636/1/TFM-G1866.pdf 3cd50ec78622bfdbea47e169fb44cad0 Attribution-NonCommercial-NoDerivatives 4.0 Internacional
