The discoloration of Carmoisine at an initial concentration of 1 g/L, by the Fenton process (Fe 2+ / H 2 O 2 ) 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, Fe 2+ and H 2 O 2 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 Fe 2+ , 194.1 mmol/L H 2 O 2 , at pH = 3. The discoloration kinetics of the carmoisine followed the BMG model. |
