The Characterization and Oxygen-Nitrogen Separation Property of Disalicylidene-1, 2-Diamino propane Cobalt（Ⅱ） Complex/Ethyl Cellulose Membrane

Disalicylidene-1, 2-diaminopropane cobalt（Ⅱ） complex was prepared and blended with EC homogeneously, and then made it a gas separation membrane. The existence of cobalt（Ⅱ） complex in membrane was characterized by UV-Vis-NIR, EPR, and XPS. The selective permeation of oxygen through the membrane was made a probe, and was explained by Dual-Mode Transport Model.
