Estudio remoción de flúor en soluciones acuosas usando grafeno funcionalizado.

Abstract

This study is developed with the main objective of studying the removal of fluoride from water sources using functionalized graphene hydrogels. Fluorine is a pollutant present in underground and surface water around the world and its negative effects on public health have represented a great challenge for governments in turn. It was decided to use graphene because it is an emerging material, with many publications made in recent years and intrinsic and adaptable characteristics that make it eye catching to science and industry. By electrochemical exfoliation of graphite sheets it pretends to obtain a graphene liquid ink. This ink will be exposed to hydrothermal digestion to obtain a 3D graphene structure (hydrogel). Finally, the fluorine contaminated water is allowed to pass through a small filter, so that it comes into contact with the hydrogel. It is expected that by ion exchange the graphene the fluoride ions.
