Facultad de Ciencias K1 Nanocomposite electrospun fibers K1 Sepiolite K1 Nitrates absorption K1 AFM AB 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 problemsfacing society today. In this work, nanocomposite fibers doped with modified sepiolite have been developed for nitrate adsorption. Their adsorptioncapacity (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 towater decontamination in this field, which reach similar capacities but in contact times between 24 and 72 hours. The nanocomposite fibers produced werefoamed 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 inthe AM-AFM mode have been tested.
