Abstract

The discoloration of Carmoisine at an initial concentration of 1 g/L, by the Fenton process (Fe2+/ H2O2) has been studied. The efficiency of this process in the discoloration of Carmoisine, as well as the influence of the reaction parameters, was discussed. The effects of initial pH, Fe2+ and H2O2 concentrations, and treatment duration on the discoloration kinetic were evaluated. Our results showed that the best discoloration efficiency has reached 94 % and was achieved in 20 minutes of treatment with 3.57 mmol/L Fe2+, 194.1 mmol/L H2O2, at pH = 3. The discoloration kinetics of the carmoisine followed the BMG model.
