Surface tensions of carbonated 2‐amino‐2‐methyl‐1‐propanol (AMP) and piperazine (PZ) aqueous solutions were measured by a surface tension meter which employs the Wilhemy plate principle. A thermodynamic model was proposed to correlate the surface tensions of both CO 2 ‐unloaded and CO 2 ‐loaded aqueous solutions by introducing the contribution of CO 2 loading into the formulation of surface tension. Based on experiments and calculations, the effects of temperature, mass fractions of amines, and CO 2 loading on surface tensions of carbonated aqueous solutions were demonstrated.
