This study investigated the effect of ultraviolet (UV) enhancement and the Fe3+-EDTA Complex on the degradation of methylene blue (MB) in Fenton-like system. By studying different variables including H2O2 concentration, Fe3+-EDTA concentration and pH value, and using MB as a model pollutant, the best experimental conditions was to investigated. Experimental results showed that it is possible to degrade MB wastewater effectively by modified UV-Fenton with Fe3+-EDTA at neutral pH. Besides, optimality condition (pH= 7, [Fe3+-EDTA] = 2 mmol/L, [H2O2] = 10 mmol/L) which were used in the modified UV-Fenton that achieves a removal of over 95% of the MB in 60 min reaction time. Therefore, this new modified Fenton system is an effective treatment for MB wastewater.
