Abstract Backgrounds and Objectives: In Fenton process, ferrous ions reacted with peroxide Hydrogen and produce very active hydroxyl radicals and high potential that its can oxidation of organic compounds such as Humic acid. Thus, the present study aimed at surveying the amount of Humic acid removed from environmental aqueous by Fenton process. Materials and Methods: In this study several parameters, such as initial Humic acid (2, 4, 8 mg/l), pH (2, 3, 4, 5), Ferrous (4, 8, 12, 16 mg/l), H2O2 (20, 40, 60, 80 mg/l) and reaction time (5, 10, 20, 40 min) to removal of Humic acid from environmental aqueous in one-liter water containers were studied. Finally, the outcome of Humic acid removal was assessed by means of TOC analyzer. Results: it was revealed that the most removal of Humic acid from from environmental aqueous could be achieved (1.969 mg/l removed) when the pH was 3, ratio of Peroxide Hydrogen per ferrous was 40/4, oxidation time was 40 minutes and initial concentration was 2 mg/l. Conclusion: It was found Humic acid can be removed effectively by Fenton Oxidation process.
