摘要： A carbon dioxide absorbent is disclosed. The absorbent comprises organic amine, amino acid, and water, wherein said organic amine comprises tertiary amine and primary amine and/or secondary amine; and wherein amino acid is excess based on a stoichiometrical ratio of organic amine to amino acid in a reaction. A method for absorbing and desorbing carbon dioxide is further disclosed. In the absorbent system provided by the present disclosure, the conversion between primary (secondary) amine and (secondary) tertiary amine can be realized under the catalytic effect of amino acid with the changing of temperature, and carbon dioxide can be absorbed and desorbed effectively under a relatively low temperature.
