Degradation of Azo Dye Orange II in Aqueous Solution by Homogeneous UV-Fenton Process with Low Concentration of Fe3+ as Catalyst
In this paper, degradation of Orange II by homogeneous UV-Fenton process with low concentration of Fe3+ as catalyst was detected. And the effects of UV light wavelength, initial pH and reaction temperature on degradation of Orange II in homogeneous UV-Fenton system were studied in detail. It was found that the arithmetic sum of the rate constants of dye degradation in Fenton and UV-H2O2 and UV was much lower than that in UV-Fenton system with low concentration of Fe3+ as catalyst. The result showed that using low concentration of metallic salts as homogeneous catalyst would be a good alternative in UV-Fenton system for wastewater treatment.
