Removal of Acid Red 88 dye from wastewater by Fenton’soxidation

In this paper, degradation of Acid Red 88 (AR-88) dye in the wastewater has been studied using Fenton’s oxidation process. The Fenton’s technique indicated satisfactory dye removal efficiency. The operating parameters such as initial pH, concentration of Fe2+, dose of H2O2 and initial concentration of dye were investigated. The optimum conditions were determined as pH=3, dose of Fe2+=3mg/L, dose ofH2O2=200mg/L and initial concentration of dye=20mg/L after 8min of reaction. The maximum removal efficiency of AR-88 dye was reached over 99%.
