The invention relates to a method for the removal of carbon dioxide from a gas flow, in which the partial pressure of the carbon dioxide in the gas flow is less than 200 mbar, whereby the gas flow is brought into contact with a liquid absorption agent, comprising an aqueous solution (A) of a tertiary aliphatic amine and (B) an activator of general formula R<SUP>1</SUP>-NH-R<SUP>2</SUP>-NH<SUB>2</SUB>, where R<SUP>1</SUP>=C<SUB>1</SUB>-C<SUB>6 </SUB>alkyl and R<SUP>2</SUP>=C<SUB>2</SUB>-C<SUB>6 </SUB>alkylene. The method is particularly suitable for treatment of flue gases and also relates to an absorption agent. |
