Kinetic Study Of Degradation Of Rhodamine B In Aqueous Phase By Fenton Process

Résumé: The main objective of this work was to study the degradation of Rhodamine B (RhB) in aqueous solution using Fenton process. Effects of various experimental parameters of the oxidation reaction of the dye were investigated. The parameters studied were the initial concentrations of FeSO4, of H2O2, and of the Rhodamine B (RhB), the temperature and the addition of salts. The optimum conditions had been determined, and it was found that efficiency of degradation of RhB obtained after 20 min of reaction was about 83.96%. The optimal parameters were: initial pH = 3; ; [H2O2]0 = 0,1 mM ; [Fe2+]0 = 0,1 mM ; for a concentration of dye [RhB]0 = 10 mg/L. The experimental results showed that the Fenton's reagent was effective for the degradation of RhB dye with a low concentration of H2O2 and Fe2+.
