Síntesis de nanopartículas de magnetita usando extracto de cáscara de papaya

Abstract

This paper studies the (Fe3O4) magnetite nanoparticles synthesis from papaya peel extract through a simple and ecological reaction. For the synthesis, the amount of glucose present in the papaya's peel is verified, because of this carbohydrate is indispensable as a reducing agent in the reaction, the synthesis is performed for three different samples which are evaluated against a commercial sample through of infrared microscopy (FTIR) and scanning electron microscopy (SEM) the last one where its size and morphology are determined, thus demonstrating that it's nanometric, besides being physically characterized with the help of magnets, thus checking their magnetic capacity. Subsequently the .dyes degradation was performed and has positive results for the brigh blue dye -, which is verified quantitatively by means of UV-Vis spectroscopy, and which is evaluated with different amounts of synthesized magnetite and over time for 2 hours.
