Removal of Malachite Green Dye from aqueous solution by Fenton Oxidation

چکیده
In order to see the influence of different variable parameters (initial pH of the solution, Fe++ concentration and H2O2 concentration) and the efficiency to remove Malachite Green dye (Basic Green 4) from aqueous solution, Fenton Oxidation method was employed. Then different parameters were studied using known concentration (150 mg/l) and initial COD (256 mg/l) of prepared dye synthetic solution in a batch mode. The results showed a very high decolorization of 99.40% and the reduction of COD upto 100 % achieved at pH 12 and Fe++ concentration and H2O2 concentration of 400mg/l and 6 ml/l. This confirms the efficient removal of dye by Fenton oxidation.
