    摘要： To provide a carbon dioxide separation composition which is excellent in carbon dioxide desorption efficiency (desorption amount/absorption amount) and durability to nitrogen oxides, and a method for separating carbon dioxide.
    A carbon dioxide separation composition, containing at least one amine compound selected from the group consisting of an amine compound represented by the following formula (1):

    wherein R 1 to R 3 each independently represent a hydrogen atom or a C 1-4 alkyl group, and an amine compound represented by the following formula (2):

    wherein R 10 , R 11 , R 12 , R 13 and R 14 each independently represent a hydrogen atom, a C 1-4 alkyl group, a hydroxy group, a hydroxymethyl group, a 2-hydroxyethyl group or a C 1-4 alkoxy group,
    a and b are each independently 0 or 1 and satisfy the relation a+b=1, and
    R 15 is a hydrogen atom, a C 1-4 alkyl group, a methoxymethyl group, a methoxyethoxymethyl group or a 2-hydroxyethyl group.
