ABSTRACT
A theoretical separation curve was derived and calculated for a hypothetical system consisting of surfactant, water, and air. The surfactant is preferentially adsorbed at the water/air interface and the surface layer is separated from the bulk solution to create a surfactant concentrate and a tailing. The separation is performed as equilibrium process, which is governed by the thermodynamic Gibbs equation. The splitting force regulates the amount and quality of concentrate. It was shown in the paper that having a well defined system it is possible to create separation curves, which can predict the results of separation.
