[Decolorization of reactive blue P-3R with microsphere-supported binuclear Manganese complex as a novel heterogeneous CWPO catalyst].
Binuclear manganese complex (MnL), with high catalytic activity, was encapsulated into ethyl cellulose microspheres via a microencapsulation technique. The characterization of the catalyst through ICP, UV-VIS, SEM and TEM revealed that MnL was well distributed within the ethyl cellulose matrix. The results of UV-VIS confirmed the structural integrity of MnL after the encapsulation process. The MnL loaded microspheres exhibited an excellent catalytic property in the oxidative decolorization of Reactive Blue P-3R, which was used to simulate the dyestuff wastewater. The dye solution was completely decolorized under the catalyzing action of these microspheres. What's more, these MnL loaded microspheres could be reused for at least 4 times and the decolorization degree of Reactive Blue P-3R was maintained above 70%. The results demonstrated the potential application of the microsphere-supported MnL as a novel heterogeneous CWPO catalyst for the decolorization of wastewater containing dyestuff.
