Emulsion Liquid Membrane
Emulsion liquid membranes are widely used for recovery of metal ions and organics due to the fast extraction and are a single-stage operation of stripping-extraction. Essentially emulsion liquid membranes are double emulsions which are made stable with surfactants. Separation of dyes using such an emulsion technique is quite novel and new, being researched only for the last one or two decades. The chapter introduces the details of the technique and the efficacy of the method in removing dye-contaminated wastewater.
