| 摘 要： | 用全自动表面张力仪测定了293.15～323.15 K温度范围内,具有不同CO2载荷的二乙醇胺(Diethanolamine,DEA)水溶液的表面张力,提出了适宜表达DEA-CO2水溶液表面张力的热力学模型,计算结果与实验值吻合良好.在实验测定和理论计算的基础上,阐明了温度、DEA浓度和CO2载荷对DEA-CO2水溶液表面张力的影响规律.

| Abstract: | In this work,the surface tensions of carbonated diethanolamine(DEA) aqueous solutions from 293.15 to 323.15 K were measured by using an automatic surface tension meter.A thermodynamic model applicable for the surface tensions of carbonated DEA aqueous solution was proposed and the calculated results agreed well with experiments.The influences of temperature,DEA concentration and CO2loading were demonstrated on the basis of experiments and theoretical calculations. |
