| dc.description | En los últimos años, el grafeno y sus derivados, como el óxido de grafeno (GO) y el óxido de grafeno reducido (rGO), han ganado gran relevancia en diversas áreas científicas debido a sus notables propiedades, lo que ha generado un creciente interés en su aplicación en campos como la medicina, la tecnología y el medio ambiente. Sin embargo, uno de los principales inconvenientes en la producción de estos compuestos, especialmente el rGO, es el uso de agentes reductores perjudiciales para la salud humana y el medio ambiente. Este estudio se enfoca en la obtención de óxido de grafeno reducido utilizando ácido ascórbico como agente reductor ecológico, además de implementar un proceso de lavado para eliminar posibles trazas residuales, permitiendo su posterior análisis mediante espectroscopía UV-visible y Raman. | |

However, one of the main drawbacks in the production of these compounds, especially rGO, is the use of reducing agents harmful to human health and the environment. This study focuses on obtaining reduced graphene oxide using ascorbic acid as an environmentally friendly reducing agent, in addition to implementing a washing process to remove possible residual traces, allowing its subsequent analysis by UV-visible and Raman spectroscopy. | |
