The present invention relates to a method for using, as a carbon dioxide absorbent, a secondary amine having a nitrile group, that is, a 3-(alkylamino)propionitrile compound. More particularly, the present invention relates to a carbon dioxide absorbent based on an amine having a nitrile functional group, and a carbon dioxide absorption method and separation method using same, wherein the 3-(alkylamino)propionitrile compound is used, as a carbon dioxide absorbent, alone or in combination with a secondary alkanolamine, the compound being a novel amine compound containing a nitrile group, which is obtained by reacting a primary alkylamine or cycloalkylamine with acrylonitrile or methacrylonitrile. The absorbent based on the 3-(alkylamino)propionitrile compound and the carbon dioxide absorption method and separation method using same, according to the present invention, not only have an excellent carbon dioxide absorption capacity and a rapid carbon dioxide absorption rate, but also allow ...
