Abstract: A description is given of an absorption medium for deacidifying fluid streams which has improved oxidation stability and comprises at least one aliphatic amine, in particular an alkanolamine, and at least one non-hydroquinoid antioxidant. The absorption medium serves for deacidifying a fluid stream, in particular an oxygen-containing fluid stream, the fluid stream being brought into intimate contact with the absorption medium in at least one absorption step.
