The objects of embodiments in the present disclosure are to provide a method capable of recovering two or more amine compounds at the same time from a gas or solution, and also to provide a method capable of analyzing the recovered amines.
The amine-recovering method comprises the steps (A) and (B). In the step (A), the gas or solution is brought into contact with a solid adsorbent so that the adsorbent may retain the amines. In the step (B), the amines retained by the adsorbent in the step (A) are eluted out by use of a basic compound-containing organic solvent. The solid adsorbent has a substituent group represented by -SO 3 M (M is H or an alkali metal).
