제목 Adsorption Behaviors of Propylamine on Activated Carbon Surfaces Introduced by Oxygen Functional Complexes
초록 Surfaces of ACFs were modified by nitric acid to introduce surface oxygen complexes and to observe the influence of these complexes on the propylamine adsorption of the ACFs. Oxygen complexes were predominantly increased, resulting in the increase of total surface acidity. However, the specific surface areas and the total pore volumes of the modified ACFs were decreased by 5 to 8% due to the increased blocking of micropores in the presence of newly introduced complexes. In spite of the decrease of textural properties, the adsorption amount of propylamine of the modified ACFs was increased around 17%. From the XPS results, propylamine was reacted with strong or weak acidic groups, such as COOH or OH existed on the ACF surfaces, resulting in forming pyridine-like or pyrrolic structures.
