Abstract: PURPOSE: A composition for absorbing carbon dioxide, a composition for improving the absorbing speed of carbon dioxide and suppressing the evaporation of ammonia, and a method for the same are provided to improve the purify of collected carbon dioxide gas and reducing the discharge of ammonia from treated mixed gas. CONSTITUTION: A composition for absorbing carbon dioxide includes an amine-based additive and ammonia water. The ammine-based additive is capable of being a compound containing two or more amine groups. The amine-based additive is capable of being a heterocyclic compound containing a secondary or tertiary amine group in a ring structure. The amine-based additive is capable of being a compound substituted with a primary amine, secondary amine, tertiary amine, or hydroxyl group. The amine-based additive is capable of being selected from 2-hydroxyl ethyl piperazine, homopiperazine, 1-methylpiperazine, 2-methylpiperazine, 1,4-dimethylpiperazine, 1,4-bis(2-hydroxyethyl)piperazine, 1-(2-aminoethyl)piperazine, 2-piperazine-1-ethanol, and a combination of the same. The amine-based additive is capable of being selected from a group including triethylene triamine, triethylene tetraamine, and the combination of the same.
