A GENERAL THEORY OF INTERFACIAL TENSION AND ITS APPLICATION TO ADSORPTION PHENOMENA,
Abstract
Existing equations have had limited success in predicting adsorption from binary solutions. Development of a theory that would describe liquid phase adsorption with certainty was desirable. An equation based on thermodynamic considerations and the bulk and surface regions of a binary solution was developed, manipulated, into linear form, and tested with data for several binary solutions, both aqueous and nonaqueous, against vapor, liquid and solid interfaces with confirmation in every case. The equation can be used to determine (1) the specific surface area of an adsorbent in the liquid phase, (2) the surface tension of a solid adsorbent at normal temperatures, (3) the molecular orientation of an adsorbent, and (4) the number of layers of thickness adsorbed.
