Visual Study on the Effect of Osmotic Pressure on the Morphology of Emulsion Liquid Membrane

Abstract:

The purpose of this paper is to investigate the effect of osmotic pressure on the morphology of emulsion liquid membrane (ELM) by the visual way. The experimental results show that osmotic pressure has great effect on the globules of emulsion liquid membrane through water diffusion between two water phases. When under isotonic pressure, the water transport trend cannot be observed. When osmotic pressure is less than zero, water transfers from the internal phase to the external phase. But when osmotic pressure is larger than zero, water transports from the external phase to the internal phase first by diffusion, then water transports from the internal phase to the external phase by the coalescence. Therefore, it is possible to tailor osmotic pressure between two water phases to keep the stability of emulsion liquid membrane when ELM is used to separate some component.
