Effective pharmaceutical wastewater degradation by Fenton oxidation with zero-valent iron, Applied Catalysis B: Environmental, Vol. 136-137, 2013, 64-690926-3373http://hdl.handle.net/10115/11590Línea Investigación: Línea 1. Procesos de depuración de aguas residualesThe pre-treatment of a pharmaceutical wastewater (PWW) by Fenton Oxidation with zero-valent iron (ZVI) and hydrogen peroxide was investigated to improve the degradation of the complex-mixture of organic compounds present in the wastewater. The influence of different crucial parameters such as the initial hydrogen peroxide concentration, the ZVI concentration and the capacity of the ZVI/H2O2 system to treat different organic loading have been evaluated. The optimal conditions for degradation led to TOC reductions of up to 80% in only one hour of treatment. This degree of organic mineralization was reached by using moderate loadings of ZVI and hydrogen peroxide (ZVI/TOC weight and H2O2/TOC molar ratios of 12 and 3.2, respectively). Moreover, the use of waste-metallic iron shavings in terms of TOC removal compared to commercial ZVI powder may be a promising and cheaper development.engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Medio AmbienteFenton processesPharmaceutical wastewaterZero Valent Iron (ZVI)info:eu-repo/semantics/article10.1016/j.apcatb.2013.01.036info:eu-repo/semantics/openAccess2390 Química Farmacéutica
