Síntesis de nanopartículas de magnetita a partir del extracto de cáscara de papaya para la degradación de colorantes azoicos en soluciones acuosas

Abstract

This document describes the Fe3O4 magnetite nanoparticles process synthesis via papaya peel extract by a simple and ecological reaction. For the synthesis, is verified the amount of glucose present in the shells since this carbohydrate is indispensable as a reducing agent in the reaction, the method is make for three different samples that are evaluated by infrared microscopy FTIR and compared with a commercial sample, in the other hand by SEM was possible see if the size and morphology corresponding to the expected results; subsequent the azo dyes degradation give positive results for the bright blue E-133 dye showing the transparency in the medium and is checked quantitatively through of UV-Vis spectroscopy.
