El proceso Fenton, es un proceso avanzado de oxidación que utiliza sales de hierro (Fe2+) solubles como catalizadores en presencia de H2O2 a pH ácido. En la presente investigación, con el objetivo de valorizar un material natural basado en óxidos de hierro proveniente de Acerías de Paz del Río en el departamento de Boyacá, Colombia, se llevó a reacción dicho material como catalizador en el proceso tipo Fenton frente a dos colorantes usados como modelo en reacciones de degradación: Cristal Violeta (CV) y Fucsina Ácida (FA). El material se caracterizó a través de diferentes técnicas, encontrándose una baja área superficial (27 m2/g), diferentes fases de hierro, dentro de las cuales predominan la siderita, goethita y hematita y una composición elemental mayoritaria para hierro y oxígeno. La evaluación de la actividad catalítica mostró que este material es capaz de reducir la cantidad de Cristal Violeta (CV) hasta el 90% y de Fucsina Ácida (FA) hasta un 80% en 8 h, partiendo en ambos casos de una concentración de contaminante de 50 mg/L, así mismo el valor de carbono orgánico total (TOC) se redujo hasta 34% en CV y 36% en FA, y en los ciclos de reúso el TOC se redujo al 46% y 51% luego del primer ciclo para el CV y la FA respectivamente. Se encontró que la cantidad de hierro lixiviado en la solución es de 6 mg/L, lo cual indica que el proceso catalítico es heterogéneo.

The Fenton process is an advanced oxidation process that uses soluble iron salts (Fe2+) as catalysts in the presence of H2O2 at acid pH. In this investigation, with the aim of valorize a natural material based on iron oxides, coming from Acerías de Paz del Río in Boyacá, Colombia, this material was used as a catalyst in the Fenton process against two dyes used as a model in degradation reactions: Crystal Violet (CV) and Acid Fuchsin (FA). The material was characterized through different techniques, finding a low specific surface area (27 m2/g), different iron crystalline phases, predominantly siderite, goethite and hematite, and a majority elemental composition for iron and oxygen. The evaluation of the catalytic activity showed that this material can reduce the amount of Crystal Violet (CV) up to 90% and of Acid Fuchsin (AF) up to 80% in 8 h, starting in both cases from a contaminant concentration of 50 mg/L, likewise, the Total Organic Carbon (TOC) value was reduced up to 34% in CV and 36% in AF, and in the reuse cycles, the TOC was reduced to 46% and 51% after the first cycle for CV and AF respectively. The amount of iron leached was found to be 5 mg/L, indicating that the catalytic process is heterogeneous.Incluye anexosMaestríaMagíster en Ciencias - QuímicaCatálisis ambientalxix, 109 páginasapplication/pdfspaUniversidad Nacional de ColombiaBogotá - Ciencias - Maestría en Ciencias - QuímicaFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá540 - Química y ciencias afines::543 - Química analíticaColoring matterCatalystswater pollutantsColorantesCatalizadoresContaminantes del aguaProceso FentonProcesos Avanzados de Oxidación (AOP´s)Cristal violetaFucsina ácidaMaterial de hierroAdvanced Oxidation Processes (AOP)Crystal violetFenton processAcid fuchsineIron oreDegradación de colorantes presentes en aguas residuales usando un mineral natural basado en óxidos de hierro como catalizadorDegradation of dyes present in wastewater using a natural material based on iron oxides as catalystTrabajo de grado - Maestríainfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/acceptedVersionTexthttp://purl.org/redcol/resource_type/TMÁngel, M., José, H., Velasco, A., Rojas, F., Hugo, V., Alicia, M., Víctor, S., Mesoporos, E.
