چکیده انگلیسی
The oxidative degradation of metal-complex Co(II) Acid Brown 159 in aqueous solution by H2O2/Fe2+ and ozone was investigated. Optimal conditions for decolorization and total decomposition processes were found for dye oxidation during H2O2/Fe2+ and ozone treatments. The full 100% decolorization is attained during first minutes of H2O2/Fe2+ and ozone oxidation processes. The complete mineralization of aqueous solutions of Acid Brown 159 dye cannot be achieved even under the optimal reaction conditions. Fenton's process appeared to be more effective in comparison with ozonation. A tentative mechanistic pathway for the oxidative degradation of Acid Brown 159 dye in aqueous solution was postulated.
