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
