Abstract

There is something intriguing and at the same time fascinating that a simple reaction (Fe2+ ions with H202), which was observed by H.J.H. Fenton over 110 years ago, proves to be very difficult to describe and understand. Yet the nature of oxidizing species obtained in Fenton reaction is still a subject of deliberation, which may be explained by the fact that it is very common in both chemical and biological systems in natural environment. Advance oxidation process (AOPs) show great promise for application in many wastewater treatments areas. AOPs are emerging technology that may be employed for specific goals in wastewater treatment. The Application of Advance Oxidation process (AOPs) for dyes wastewater treatment is the focus. Fenton reagents as one of AOPs were applied for the minimization of organic content of coloured synthetic wastewater. Methylene Blue (MB) Dye was used as the model organic pollutants. Fenton type process was examined in orders to established optimal operating condition (pH, Hydrogen Peroxide (H202) concentration, ferrous ion catalyst concentration (Fe2+) [Fe2+] / [H202] Fenton ratio, dye concentration and temperature for maximum degradation of the investigated simulated coloured wastewater. It was found out that optimum conditions were obtained at pH of 3, hydrogen peroxide of concentration 70mM, Iron catalyst concentration of 4mM, the Fenton ratio [Fe2+] / [H202] of 1: 17.5 and temperature of 45°C. Degradation of Methylene blue dye from textile wastewater using Fentons reagent is very promising since the system achieved high reaction yield, compared to other and there is no needs for special treatment.
