Titanium dioxide (TiO2) was used, modified with iron oxide (III) as photocatalyst, supported on polymethyl methacrylate plates, arranged in two reactors with volumetric capacities of 15.0 ml and 1.0 l. The degradation process was studied using two analysis methods: Photometric detection and gravimetric partition. Degradation percentages of 91.2% and 98% were obtained in field samples and synthetic mixtures respectively, with 4 h times; this allows for assessment of this technique's impact on the treatment of produced water in the oil industry, seeking for an alternative to the methods for treating water contaminated with hydrocarbons.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[RESUMEN En esta investigación se llevó a cabo la degradación de hidrocarburos totales en mezclas sintéticas de agua y en muestras obtenidas del flujo de entrada de un skimmer (agua de producción), por medio de fotocatálisis heterogénea. Se usó dióxido de titanio (TiO2) modificado con óxido de hierro (III) como fotocatalizador, soportado en láminas de polimetilmetacrilato, dispuestas en dos reactores con capacidades volumétricas de 15,0 ml y 1,0 l. El proceso de degradación fue estudiado mediante dos métodos de análisis: Detección fotométrica y partición gravimétrica. Se obtuvieron porcentajes de degradación de 91.2% y 98% en muestras de campo y mezclas sintéticas respectivamente, en tiempos de 4 h; los cuales permiten evaluar el impacto de esta técnica en el tratamiento de agua de producción de la industria petrolera, buscando ser una alternativa a los métodos de tratamiento de aguas contaminadas con hidrocarburos.]]></p></abstract>
