Abstract为研究重铬酸钠(Na2Cr2O7)对CO2溶解的影响, 本文在带有搅拌的气液相高压平衡釜内, 采用静态法测定了温度在313.2-333.2 K, 压力在0.1-1.9 MPa 范围内, 重铬酸钠浓度分别为0、0.361、0.650、0.901 mol·kg-1 时, CO2 在Na2Cr2O7溶液中的溶解度. 结果表明: (1) Na2Cr2O7对CO2 的溶解有盐析效应; (2) CO2 在Na2Cr2O7溶液中的溶解符合亨利定律, 并且CO2溶解度是温度和Na2Cr2O7浓度的函数, 且用改进的Setschenow方程和Peng-Robinson-Pitzer (PR-Pitzer)方程拟合了在此温度、压力及重铬酸钠浓度范围内的实验数据, 拟合效果较好, 并且其平均相对误差分别为4.24%和3.32%.
