Aplicación de nanofibras de celulosa impregnadas con cyanex 923 para la recuperación de itrio en fases acuosas.

Abstract

Rare earth elements are widely used in the nuclear, metallurgical, medical, electronic, ceramic, computer technology and other fields due to their unique properties. One of the main rare earth elements is yttrium, which is an element that belongs to the lanthanide family. Yttrium is used in the electronics industry, lasers, phosphor powders, due to its higher conductivity. Also, yttrium is often used in large amounts, including equipment and tools such as fluorescent lights, eyeglasses, and color televisions. One of the problems that science seeks to solve is to develop separation technologies for these rare earth metals through sustainable and environmentally friendly processes. One of the friendliest technologies is that related to bioadsorption, due to it uses materials of organic origin. Cellulose and one of its main derivatives such as cellulose nanofibers are one of the most popular materials in adsorption applications.
