| 英文摘要 | The osmotic coefficients of the Na2CrO4-H2O system at 353.15 K were determined using isopiestic method ranging from 0.05 to 7.683 mol.kg(-1). The experimental osmotic coefficients were excellently correlated with Pitzer equation to obtain the interaction parameters, the activity coefficients, and the solubility product for Na2CrO4. Furthermore, the solubility of Na2CrO4 in NaOH solutions at 353.15 K was predicted using binary parameters, and the predicted values agree with the experimental data, demonstrating the Pitzer equation is capable of optimizing the processes for the removal and recovery of sodium chromate in NaOH solutions at high temperature. |
