Resumen
Los efluentes procedentes de la parbolización del arroz contienen compuestos no biodegradables que resultan tóxicos para los ecosistemas acuáticos. En este estudio, se utilizó un catalizador de Fe altamente disperso sobre sílice obtenida de cascarilla de arroz (5Fe@SiO2) para la reacción de oxidación del fenol presente en aguas residuales de la parbolización del arroz. La reacción se hizo a 25 °C y a presión atmosférica. El catalizador alcanzó una reducción de la demanda química de oxígeno (DQO) del 67±3 %, una mineralización del 68,4±2,2 % y una conversión de fenol del 81,4±2 % después de 36 horas. El rendimiento del catalizador en la oxidación de fenol demuestra el potencial de aplicación del material en el tratamiento de aguas residuales. Dichos sistemas constituyen una estrategia para la conservación de los recursos naturales y la preservación de la biodiversidad en Colombia. Este estudio constituye una contribución a la estrategia de transición hacia la economía circular.
