Solubility of SO₂, CO₂in DMSO+Mn²⁺mixture solvents and EOS model

Abstract

The electrolyte equation of state (EOS) in [Phys. Chem. Liq., 44(1), 83, 2006] has been applied which describes the solubility of SO 2 in DMSO þ Mn 2þ mixture solvents. With the assumptions used in previous applications of our model to SO 2 system, the EOS in this study is extended to the system of SO 2 and CO 2 . In this article, on the basis of solubility measurement of dilute SO 2 , CO 2 in DMSO þ Mn 2þ mixture solvents, an extended EOS model is described. In order to test the correctness of our model, the data of gas-liquid equilibrium of such a multicomponent system have been fitted with the binary interaction parameters in the model, and the solubilities calculated by the model show good agreement with the experimental data.
