英文摘要 | The solubility of CO2 in aqueous Na2Cr2O7 solutions of different concentrations (0, 0.361, 0.650, and 0.901 mol.kg(-1)) was measured in a stirred vapor-liquid high-pressure equilibrium cell using the static method at temperatures and pressures in the ranges of 313.2 to 333.2 K and 0.1 to 1.9 MPa, respectively. The results indicated that the phenomenon of CO2 dissolved in aqueous Na2Cr2O7 could be interpreted according to a "salting-out effect". Furthermore, our solubility data for CO2 in aqueous Na2Cr2O7 was in agreement with Henry's law, and the Henry constant appeared to be a function of temperature, pressure, and the concentration of Na2Cr2O2. Two thermodynamic models were applied to correlate the experimental data, including the modified Setschenow and Peng-Robinson-Pitzer equations, and the averaged relative deviations were found to be 4.24% and 3.32%, respectively. |
