| Abstract: | A comprehensive review of recent advances in study on thermodynamic models for real electro-lyte solutions is presented. The differences between primitive and non-primitive electrolyte models are dem-onstrated. Some new thermodynamic models for electrolyte solutions based on the mean spherical ap-proximation and perturbation theory are introduced. An extended scaled-particle theory and modified Clegg-Pitzer equation are presented for physical and chemical absorption processes with mixed solvents, respec-tively. A pseudo one-component two-Yukawa equation of state is used for the aqueous two-phase extraction process in charged colloidal systems. |
