Catalytic Properties of Manganese Complex of Cyclic Polyamine Encapsulated in Ethyl Cellulose Microcapsules
CHEMICAL JOURNAL OF CHINESE UNIVERSITIES-CHINESE(2014)
摘要
Manganese complex of cyclic polyamine (MnAcL) was encapsulated within ethyl cellulose (EC) microcapsules via emulsion solvent evaporation technique. The morphology of MnAcL-EC microcapsule was characterized. The results of UV-Vis confirmed the structural integrity of MnAcL in EC microcapsules. The catalytic property of the as-prepared MnAcL-EC microcapsules was evaluated by the oxidation of C. I. Reactive blue 49 with H2O2. It was found that both the particle size and the pores on the surface of the spheres increased after the reaction. However, the amount of MnAcL in EC microcapsules was almost not changed, as measured by the elemental analysis. It was suggested that the oxidation of C. I. Reactive blue 49 was catalyzed successfully by the encapsulated MnAcL inside the microcapsules. What's more, the as-prepared MnAcL-EC microcapsules could be reused for at least 4 times. These results demonstrated that the MnAcL-EC microcapsule prepared in this paper could be applied as a high efficient catalyst.
