The Monte Carlo method was used to simulate the potential energy, intermolecular forces, radial distribution function, density profile, surface thickness and surface tension for a TY fluid at different temperatures. The results for a TY fluid are compared to those for a Lennard-Jone fluid, which shows that the surface properties are more sensitive to the intermolecular potential than the bulk properties and the repulsive action with a shore range can also influence the surface properties.展开更多

The differences between primitive and non-primitive electrolyte models are demonstrated. Some new thermodynamic models for electrolyte solutions based on the mean spherical approximation and perturbation theory are introduced. An extended scaled-particle theory and modified CleggPitzer equation are presented for physical and chemical absorption processes with mixed solvents, respectively. A pseudo one-component two-Yukawa equation of state is used for the aqueous two-phase extraction process in charged colloidal systems.展开更多
