Background and Aim: Nowadays, regarding the increased human and geological activities, concentrations of toxic and carcinogenic disinfectant by-products– like Trihalomethanes -which have an organic base, in drinking water sources, has worryingly increased. Thus, the present study aimed at surveying the amount of dissolved organic carbon (doc) removed from aqueous solution by Fenton process. Materials and Methods: In this descriptive study, the outcome of removing dissolved organic carbon derived from natural water with initial concentrations 2, 4, and 8 mg/l using one-liter water containers by means of Fenton Process at PHs 2, 3, 4, and 5 due to adding 20, 40, 60, and 80 mg/l of H2O2 and Ferrous ions with 4, 8, 12, and 16 mg/l concentrations at oxidation time 5, 10, 20, and 40 minutes was calculated. Finally, the outcome of carbon removal was assessed by means of TOC analyzer. Results: It was found that the most outcome of dissolved organic carbon removal (about 97%) belonged to 10/1 H2O2 and Ferrous ion , while dissolved organic carbon PH was 3 and its initial concentration was 2mg/l and oxidation time was 40 minutes. Conclusion: Generally speaking, it was confirmed that the improved Fenton Oxidation Process can efficiently be used to refine water containing dissolved organic carbon. The method was found to be highly and relatively fast compared to conventional existing techniques and also, it can be concluded that the Fenton process has the potential to be utilized for the cost-effective removal of DOC from water and wastewater.
