“…In chemical removal of pharmaceuticals, Fe and Mn play important roles as oxidants, reductants, or catalysts such as Fe(II) in Fenton processes (Kochi, 1967;Guan et al, 2010;Chelliapan and Sallis, 2013;Remucal and Ginder-Vogel, 2014;Segura et al, 2015). Chemical removal of pharmaceuticals in water treatment occurs through chemical oxidation via oxidizing agents (Fe(III), Fe(VI), Mn(IV), Mn(VII)), or chemical reduction via reducing agents like nZVI to degrade a compound or a group of compounds (Lee et al, 2009;Guan et al, 2010).…”

“…In these processes, pharmaceuticals and other micropollutants can be removed via oxidation (Correia de Velosa and Pupo Nogueira, 2013;Segura et al, 2013;Shirazi et al, 2013). For example, ZVI and nZVI are used as a catalyst in Fenton's reaction with H 2 O 2 to remove pharmaceuticals (Segura et al, 2013;Shirazi et al, 2013) and other pollutants (Kowalski and Sogaard, 2014;Li et al, 2014;Segura et al, 2015). Under acidic conditions (pH < 3), ZVI is oxidized to Fe (II) on the surface of the metal and then Fe(II) catalyzes the Fenton process.…”

Pharmaceuticals are detected at trace levels in waters. Their adverse effects on aquatic ecosystems and human health demand novel pharmaceutical removal technologies for treating wastewater effluents. Iron (Fe) or manganese (Mn) may play important roles in these new technologies since these metals are abundantly available at low costs and are known to contribute to organic conversions via physico-chemical, chemical, and biologically related processes. Few reviews describe and discuss Fe-or Mn-based technologies for the purpose to remove pharmaceuticals from water. Therefore, we review the current literature sorted into the three removal mechanisms, that is., through physico-chemical, chemical, and biological processes. The principals, performance, and influential parameters of these three types of technologies are described. Current and potential applications of these technologies are critically evaluated in order to identify advantages and challenges. In addition, the Fe-or Mn-based technologies which are currently not used but promising to further develop to remove pharmaceuticals cost efficiently are proposed.

“…Además, debe realizarse a valores de pH cercanos a 3, lo cual involucra costos continuos de inversión en reactivos. Una alternativa para evitar esta situación es emplear el hierro cero valente (ZVI de su acrónimo en inglés) en estado metálico (Segura et al, 2015). Diversos trabajos han reportado la eficiencia del ZVI en la mineralización de compuestos halogenados orgánicos, clorofenoles, compuestos nitroaromáticos, pesticidas, y suelos contaminados con explosivos (Cheng et al, 2015;Ghauch et al, 2001;Johnson, Scherer and Tratnyek, 1996).…”

“…Estas limitaciones restringen las aplicaciones del método Fenton. El proceso Fenton heterogéneo ha sido desarrollado para su uso como un método alternativo y el ZVI ha demostrado ser eficaz como catalizador Fenton (Segura et al, 2015). Por otro lado, los procesos compactos e intensificados, basados en reactores de lecho fluidizado (FBR), pueden ser una alternativa eficaz para la eliminación de contaminantes en el agua utilizando ZVI como catalizador.…”

“…Por ejemplo, Grcic et al (2012) evaluaron el proceso foto-Fenton con ZVI para degradar el colorante Reactive Black (RB1), con una concentración inicial de 140 mg/L, obteniendo una degradación de colorante y carbono orgánico total del 99,42% y 64% respectivamente. Por otro lado, Segura et al (2015) evaluaron aguas residuales "reales" de la industria farmacéutica mediante tratamiento foto-Fenton heterogéneo, usando ZVI, lograron una mineralización del 100% de los contaminantes. Sin embargo, los autores diluyeron la muestra original a un valor de COT inicial de 100 ppm.…”

ResumenEn la presente investigación se utilizó el proceso Fenton heterogéneo, con hierro cero valente (ZVI) en estado metálico, en un reactor de lecho fluidizado para el tratamiento de aguas residuales de una industria textil. El objetivo fue optimizar los siguientes parámetros de operación: concentración inicial de colorante, concentración de H2O2, pH, cantidad de ZVI, y radiación UV, para maximizar la eliminación de colorante y materia orgánica. Inicialmente, se usó un diseño de experimentos factorial fraccionado, con la finalidad de encontrar los factores más influyentes. Posteriormente, para su optimización, se empleó la Metodología de Superficie de Respuesta acoplado a un diseño experimental Box-Behnken. Las condiciones óptimas obtenidas fueron: concentración inicial del colorante: 881 mg/L, pH: 5, concentración de ZVI: 5,31 g/L, y concentración de H2O2: 0,86 mL/L. A estas condiciones se realizó un estudio cinético que demostró que es posible degradar el 100% colorante y el 80,83% de la demanda química de oxígeno en 150 minutos de reacción. Palabras clave: hiero cero-valente; Fenton; aguas residuales; optimización; diseño Box-Behnken Degradation of Yellow 12 Dye in Industrial Wastewater using Zero-Valent Iron, Hydrogen Peroxide and Ultraviolet Radiation AbstractThe Fenton heterogeneous process in a fluidized bed reactor using Zero Valent Iron (ZVI), in the metallic state, for the treatment of textile wastewater has been used an analyzed. The aim of this work was to optimize the following operating parameters: initial dye concentration, H2O2 concentration, pH, amount of ZVI, and UV radiation, for the removal of dye and organic matter. At first, a fractional factorial experimental design allows defining the most influential factors. After that, they were optimized using the Response Surface Methodology coupled to the Box-Behnken experimental design. The optimal conditions were found to be as follows: initial dye concentration, 881 mg/L; pH 5; ZVI concentration, 5,31 g/L; H2O2 concentration, 0,86 mL/L. At these conditions, the degradation kinetics was performed, reaching 100% and 80,83% of dye and chemical oxygen demand respectively, in 150 minutes of reaction.
