Abstract :

In this study, the Fenton process was used to investigate the color removal efficiency of Acid Red 52 and Basic Red 18 dye solutions by direct chemical oxidation. Color and chemical oxygen demand (COD) was successfully removed more than 99% and up to 92% respectively. This article would provide an easy assessment of the viability of using Fenton reagent in acidic conditions, so it is a promising and easy method for the fairly degradation of the BR.18 and AR.52 dye in synthetic wastewater. Parameters such as dose of H2O2:1.5g/L, concentration of Fe2+: 8 mg/L as a catalyst, initial pH:3, initial dye concentration (10-500mg/L) and reaction time (18min) have been studied. The proposed system was a viable alternative to some of the more conventional forms of chemical treatment of dye solutions. Using UV-VIS spectra and COD analysis showed a good mineralization and fairly complete degradation of dye
