Kinetic Study on Photocatalytic Decolorization of Methyl Orange Aqueous Solution with KIO₄ under UV Irradiation

Abstract:

It has been generally agreed that methyl orange (MO) can be effectively decolorized in KIO₄homogeneous reaction system under UV irradiation. The knowledge on the kinetics of the system possesses both practical and theoretical values. Decolorization efficiency of MO increases as the loading of KIO₄increases and has no an optimal amount of KIO₄ in this case. The decolorization reaction manifests the first order with lower concentration and the zero order with higher concentration. As the initial concentration goes up, the order of the reaction is reduced from 1 to 0.
