It was instrumentally characterized by elemental analyses, IR, UV-VIS, XPS and ESR spectroscopy. It was demonstrated that the immobilization of Cosalen was realized through the coordination of the amino group in Chitosan with the Co (Ⅱ) in the CoSalen complex. It binds molecular oxygen reversibly in the solid state through the vacant sixth coordination site.展开更多
