摘要：
A mathematical model based on the extended Debye-Huckel equation is established for representing the equilibrium solubility of CO2 in aqueous 2-amino-2-methyl-1-propanol (AMP) solutions. The parameters of the model are obtained as well. The predicted values are in good agreement with the available experimental data. The reaction equilibrium constants of CO2 with aqueous AMP solutions and the stability constant of the carbamate are estimated using this model. The results indicate that the reaction of CO2 with aqueous AMP solutions to form the aminobase and bicarbonate ions is the dominant reaction. This work is useful for further investigations of the kinetics of the absorption of CO2 by aqueous AMP solutions.
