摘要：Ornstein-Zernike (OZ) integral equation is solved for unsymmetrical sticky electrolyte solutions with overlap at various distances between ions equal to or less than the collision diameter. Based on the mean-spherical approximation (MSA), all correlation functions and thermodynamic properties can be expressed explicitly in terms of the sticky parameters obtained through a self-consistent procedure. With the reference of an ideal-gas mixture, numerical results of excess internal energy, excess Helmholtz function, osmotic coefficient and activity coefficient for mixtures with stickiness between oppositely charged ions as well as between identically charged ions are presented.
