| 中文摘要 |
| 以微胶囊技术为负载手段,将一种具有高效催化氧化活性的双核锰配合物MnL负载到了乙基纤维素微球中,采用电感耦合等离子发射光谱仪(ICP)、紫外可见(UV-VIS)光谱扫描、扫描电镜(SEM)、透射电镜(TEM)等表征测试手段对该微球负载催化剂进行了相关的形态结构表征,发现催化剂MnL在乙基纤维素微球基质内分散良好,并保持了其原结构的完整性. 将制备的该MnL负载微球用于催化活性蓝P-3R溶液模拟染料废水的氧化脱色反应,表现出了很好的催化氧化性能. 催化氧化脱色实验发现,其不仅可以催化活性蓝P-3R溶液至完全氧化脱色,并具备一定的可循环利用性,在经过4次循环使用后仍可催化活性蓝P-3R溶液达到70%以上的氧化脱色率,可以作为一种新型的非均相CWPO催化剂用于染料废水的脱色处理. |
| 英文摘要 |
| 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. |
