Decolorization property of Fe-Mo-Si-B ribbons with different structures was investigated, and kinetic analyses elucidated that the decolorization process could be described by a pseudo-first-order kinetic model. Amorphous ribbons were proved to decolorize Acid Orange II solutions much more rapidly than amorphous/nanocrystalline ribbons at the same temperatures. Activation energies of the decolorization process by amorphous ribbons and amorphous/nanocrystalline ribbons were obtained according to Arrhenius equation, and they were proved more or less the same because of the existence of amorphous phase in both ribbons, while the different reactive site amount was considered to lead to the different decolorization rates for the two ribbons with different structures.
