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 solubility of CO2 in aqueous sodium bicarbonate solution at different temperatures and pressures was experimentally studied. The calculated solubility data were modeled using a newly established thermodynamic model and compared with the improved P-T equation. The results show that the new thermodynamic model is in good agreement with the experimental data. Especially under high pressure, the model can give better results than the improved P-T equation.
