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.
