Abstract

Abstract: The life time of oil and water films has been measured using the single dropmethod. A oil phase and surfactant,kerosene,Span-80, and TBP were used. It is foundthat water films are very unstable and easily breakable. The occurance of re- emulsificationand difficuIt occurance of occlusion swelling have been discussed.A microdrop technique isproposed to avoid entrainment swelling in liquid surfactant membrane operation.

Key words: liquid surfactant membrane, W/O emulsion, swelling, mechanical entrainment, occlusion
