Measurement of surface tension of desulfurization solution and thermodynamic model-(I)

According to the need of industrial design and application of new desulfurization technique, we determine surface tension of dilute SO₂ mixture gas in DMSO and DMSO?+?Mn²⁺ mixture absorbents, and establish their thermodynamic model based on experimental data, and the surface tension calculated by the model shows good agreement with experimental data.
