Abstract

A carbon dioxide absorbent, a preparation method therefor and a use thereof. The absorbent comprises a component A, a component B and a solvent, the component A being an imidazole-modified amino acid ionic liquid; a cation of the ionic liquid is an imidazole cation, the imidazole cation having a structure as shown in formula (I), where R1, R2, R3, R4 and R5 each independently being hydrogen or a C1-C10 straight-chain or branched alkyl; the anion of the ionic liquid is selected from sarcosine, lysine, valine or alanine; the component B is selected from aminoethylethanolamine, triethanolamine or N-methyldiethanolamine; the solvent is an aqueous solution of alcohol, the volume concentration of alcohol thereof being 5-15%. Use of the carbon dioxide absorbent in capturing carbon dioxide can improve selectivity and acid gas load during carbon dioxide capture, and reduce energy consumption.
