PURPOSE: A method for isolating carbon dioxide included in exhaust gas into deep seabed is provided to increase the dissolution rate of exhaust gas containing carbon dioxide by dissolving the exhaust gas in deep seawater of a low temperature. CONSTITUTION: A method for isolating carbon dioxide included in exhaust gas into deep seabed comprises the steps of: cooling exhaust gas containing carbon dioxide; supplying the exhaust gas to an absorbing tower (2) filled with an absorbent (3) represented by AMO2; discharging exhaust gas without carbon dioxide through a chimney (6); heating carbon dioxide absorbed on the absorbent; collecting emitted carbon dioxide in a carbon dioxide collecting tank (8); and dissolving the emitted carbon dioxide in seawater in order to isolate the carbon dioxide into deep seabed. In AMO2, A is an alkaline metal such as Li, Na, K, Rb, and Cs; and M is a metal such as Mn, Fe, Co, Ni, and Cu.
