摘要
实验研究了ＣＯ２在不同温度、压力下在碳酸氢钠水溶液中的溶解度，并对所测定的溶解度数据用新建立的热力学模型进行了模型计算，并同改进的Ｐ－Ｔ方程进行了比较。结果表明新热力学模型的计算结果与实验数据吻合较好，尤其在压力较高时，该模型能给出优于改进的Ｐ－Ｔ方程的计算结果。
The Solubilities of carbon dioxide in electrolyte solutions containing sodium bicarbonate were determined at various temperatures and pressures. A newly established thermodynamic model was used to calculate the solubilities of CO 2 in the solutions. The results showed satisfactory agreement with the experimental data. Particularly, the new thermodynamic model gave better results than the modified P T model under high pressures.
