The present invention relates to a carbon dioxide absorbent comprising an oxygen-containing diamine, a cyclodiamine, and a polyalkylene glycol dialkyl ether. The carbon dioxide absorbent according to the present invention can improve the carbon dioxide absorbing ability, absorption rate, and reproducibility thereof at the same time by using the oxygen-containing diamine as a main absorbent, the cyclodiamine as a rate enhancer, and the polyalkylene glycol dialkyl ether as a fine disproportionation agent and a reproduction promoter. |
