Kinetic and thermodynamic studies of fenton oxidative decolorization of methylene blue.

The need for light intensity has made dye degradation very costly for industry. In this work, Fenton reagent was used for the efficient degradation of an aqueous solution of dye without the need for a light source. The influences of the pH of the media, the initial concentrations of Fe, HO, and methylene blue (MB) dye; in addition to temperature on the oxidation of MB dye were studied.
