ABSTRACT
The factors affecting the adsorptive bubble separation of materials are discussed and the variety of applications surveyed. Foam separation or fractionation, bubble fractionation, and solvent sublation techniques are summarized. Examples of the separation of low concentrations of biological materials, cationic and anionic species, and organics from their solutions are presented. The factors of inherent surface activity or complexation of the species to be separated with a surface-active substance (surfactant), flow rates of the phases, concentration of species, pH, and interfacial properties of the two phases are discussed relative to their effect on the separation.
