Modelling of removal of surfactants from liquid solutions in a bubble column
Results in Engineering, 2022 This paper proposes a theoretical model for the separation of a surfactant from water in a bubble column. The proposed model includes both mass balance and adsorption thermodynamics of surfactants on bubble surfaces in the liquid solution (e.i.
