Sulfides usually found in the wastewater produced by chemical and petrochemical industries such as tanneries, refineries, polymer industries. Removing sulfides from the wastewater is currently a big challenge to the industries because sulfides are soluble in water and various research and technologies have been studied and developed in order to remove sulfides content. In this project, the author is focusing on removing sulfides through oxidation process by using hydrogen peroxide as an oxidizing agent with the presence of nano-particles ferric oxide as a catalyst. Nano-materials are increasingly gaining the attention of the scientific community and also public due to their various applications in the industries for example as a catalyst. In this project, author will developed the procedure in preparing ferric oxide nano-particle as a catalyst and the application of it in sodium sulfide oxidation process. Basically three stages are involved, the synthesization, characterization and application. In application stage, the author will study two parameters of the oxidation rate that is catalyst loading and sulfide concentration. The effect of these parameters will be study by varying the variables for these parameters. The results shows that after the more catalyst added, the oxidation process increase by time and removal of sulfide can be achieve faster. The objectives for this project are to successfully produce nano-particle ferric oxide as catalyst and to apply it in the sulfide oxidation process. in
