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.spahttps://v2.sherpa.ac.uk/id/publication/issn/0716-8756Chemical oxygen demandChemical reactorsDegradationFluid catalytic crackingFluidized bed processFluidized bedsIronOptimizationOxidationReaction kineticsStatisticsUltraviolet radiationWastewaterWastewater treatmentBox-Behnken designBox-Behnken experimental designFentonFractional factorial experimental designIndustrial wastewatersInitial dye concentrationResponse surface methodologyZero-valent ironChemicals removal (water treatment)info:eu-repo/semantics/article2021-04-16Gilpavas, E.Medina, J.Dobrosz-Gómez, I.Gómez, M.Á.10.4067/S0718-07642016000300004
