Abstract:
Heterogeneous photo-Fenton process using LiFe(WO(4))(2) as catalyst was studied to degrade Methylene blue (MB) dye in aqueous solution. The results indicated that LiFe(WO(4))(2) could effectively catalyze the decolorization of MB in the presence of UV light and H(2)O(2). The effects of different parameters such as amounts of catalyst, H(2)O(2) concentration, initial pH of the dye solution, initial dye concentration and UV light intensity on the decolorization efficiency of the process were investigated. It was found that LiFe(WO(4))(2) possessed a wide applicable pH range. X-ray photoelectron spectroscopy (XPS) was applied to investigate the transformation between Fe(III) and Fe(II). It was also observed that catalytic behavior could be reproduced in consecutive experiments without a considerable drop in the process efficiency.
