Aplicación de nanofibras de celulosa oxidada mediante reactivo tempo para la recuperación de itrio en fase acuosa

Abstract

Rare earth elements (REE) are made up of a group of 17 elements divided into two groups: light rare earth elements and heavy rare earth elements. REEs are elements applied to various technologies of the modern world. Today yttrium has played a very important role in the development of innovative new technologies, including fluorescent lamps and liquid crystal displays. On the other hand, cellulose and nanocellulose constitute one of the most abundant biodegradable materials in the world, constituting one of the best options in the search for sustainable materials. The main objective of this experimental work is to apply oxidized cellulose nanofibers by chemical activation TEMPO, for the recovery of rare earths (yttrium) in aqueous solutions, to prepare the adsorbent material from cellulose nanofibers with TEMPO, to characterize the cellulose adsorbent material oxidized by Boehm titration, carry out pH and adsorption isotherm studies with the adsorbent material to determine the adsorption capacity in the recovery of rare earths (yttrium) and be able to analyze and interpret the results obtained through mathematical adsorption models.
