The life time of oil and water films has been measured using the single drop method.A oil phase and surfactant,kerosene,Span-80, and TBP were used.It is found that water films are very unstable and easily breakable.The occurance of re-emulsification and difficuIt occurance of occlusion swelling have been discussed.Amicrodrop technique is proposed to avoid entrainment swelling in liquid surfactant membrane operation.
- liquid surfactant membrane,
- W/O emulsion,
- swelling,
- mechanical entrainment,
- occlusion
