Abstract
Cobalt-tetracarboxyl-phthalocyanine (CoTcPc) immobilized onto magnetic Fe3O4 chitosan microsphere (CoTcPc-chitosan/Fe3O4) was synthesized via a simple immersion method, and its performance on the degradation of organics (methylene blue) in the presence of air and fluorescent light was examined. Characterization results obtained from FT-IR and XPS showed that the combination of CoTcPc and magnetic Fe3O4 chitosan microsphere was achieved effectively by the coordination, hydrogen, and electrostatic adsorption bond. Moreover, the observed catalytic performance also revealed that the MB was removed entirely in 6 h with CoTcPc-chitosan/Fe3O4 as the catalyst. The stability and reusability were further evaluated, and results demonstrated that the catalyst remained active after the fourth reaction for in the same conditions. Moreover, the catalyst could be separated by an external magnet. Therefore, the CoTcPc-chitosan/Fe3O4 catalyst has potential application in the field of wastewater treatment.
