Abstract
In this work, degradation of C.I. Reactive Orange 7 dye in aqueous solutions was investigated. The electrolysis process optimized based on titanium electrode coated with SnO2 nanoparticles (nano-SnO2/Ti) as anode using response surface methodology. The nano– SnO2/Ti electrode was prepared using electrophoretic deposition (EPD) method and characterized by field emission scanning electron microscopy (FE-SEM). The initial pH, current density, reaction time and electrolyte concentration were selected as independent variables in central composite design while color removal efficiency was considered as the response function. Based on analysis of variance (ANOVA), the coefficient of determination value (R2=0.987) was high showing that the experimental values fitted well with the predicted values. In optimum conditions, maximum color removal efficiency (90.1%) was obtained after 25 minute; and the total organic carbon (TOC) was reduced to 32.2% after 60 minute.
