Stability of foams and emulsions is of great importance in a large number of applications such as mineral processing, food stabilization and oil recovery. In many of these applications, inorganic salts are present in the aqueous phase along with surfactant. These salts strongly influence the adsorption characteristics of ionic surfactants. Stability of aqueous foams and hexane-in-water emulsions prepared with aqueous solutions of an anionic surfactant (viz. SDS) and three 1:1 salts (viz. LiCl, NaCl and CsCl) was studied in this work. The ion-specific behavior of the salts was the main focus...
