MODIFICATION OF SUGARCANE BAGASSE DERIVATIVES WITH SUPERPARAMAGNETIC IRON OXIDE NANOPARTICLES, FOR THE EXTRACTION OF HYDROCARBONS.
In this work, composites of magnetite nanoparticles embedded in sugarcane bagasse are obtained and characterized. The quasi-spherical shaped iron oxide nanoparticles, obtained by chemical methods, as well as the composite samples were physically characterized by different techniques. The diffraction...

The quasi-spherical shaped iron oxide nanoparticles, obtained by chemical methods, as well as the composite samples were physically characterized by different techniques. The diffraction patterns of the samples together with the EDX mapping of iron atoms on the surface of the samples confirm the homogeneous distribution of nanoparticles in these materials. The resulting composite materials retain the adsorption/absorption capacity of the bagasse as well as the superparamagnetic properties of the magnetite nanoparticles. These two combined properties facilitate the application of the nanocomposites as a hydrocarbon adsorbent material, with the potential to be easily extracted from the medium by means of an external magnetic field. The magnetic extraction of hydrocarbons broadens the versatility of the applications of the composite material described here, facilitating its dispersion in large areas of water without the need of barriers for its collection, representing a wonderful alternative for the remediation of uncontrolled oil spills. En este trabajo se obtienen y caracterizan materiales composites formados por nanopartículas de magnetita ensambladas en bagazo de cana de azucar. Las nanopartículas de dicho (oxido de hierro obtenidas por metodos químicos presentan una forma cuasiesferica, y al igual que las muestras de los composites, fueron caracterizadas físicamente mediante diferentes técnicas físico-químicas. Los patrones de difraccion junto al mapeo EDX de átomos de hierro en la superficie de las muestras, confirman lá distribucion uniforme de nanopartículas en estos materiales. Los materiales compuestos resultantes conservan lá capacidad de adsorcion/absorcion del bagazo así como las propiedades superparamagneticas de las nanopartículas de magnetita. Estás dos propiedades combinadas facilitan lá aplicacion del nanocomposite como material adsorbente/absorbente de hidrocarburos, con potencial para ser extraído fácilmente del medio acuoso utilizando un campo magnético externo. La extraccion magnética de hidrocarburos amplía la versatilidad de las aplicaciones del material compuesto aquí descrito, facilitando su dispersion en grandes extensiones de agua sin necesidad de barreras para su recogida, representando una magnífica alternativa para la remediacion de vertidos incontrolados de hidrocarburos. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: Y custom: Copyright of Revista Cubana de Física is the property of Universidad de La Habana and its content may not be copied or emailed to multiple sites without the copyright holder's express written permission.
