Abstract:

This study focuses on the homogeneous Fenton oxidation of the synthetic azo-dye Orange G as a model compound. The impact of initial TOC, hydrogen peroxide and catalyst concentrations and of temperature on mineralization and efficiency in the use of hydrogen peroxide is addressed. Dissolved oxygen concentration is monitored as an indication of the efficient use of H2O2 in the process. A two-stage lumped kinetic model is proposed to address the effect of initial TOC, catalyst and oxidant concentrations and temperature on total organic carbon consumption. Temperature increase and dosification of the oxidant are evaluated and compared as process intensification strategies. © 2013 Elsevier B.V.
