Emulsion liquid membranes are found to be one of most efficient methodologies in the field of separation and work on the principle of concentration difference. The key parameters for wide acceptance and use are high selectivity and high enrichment factors. The distinguishing feature is that the resulting droplet size is controlled primarily by the choice of the membrane and not by the generation of turbulent droplet break-up. This article provides a review on the membrane emulsification process for the dyes removal. The present review highlights the latest emulsion liquid membranes for the separation of dye from textile industry waste water. The study on membrane synthesis methodology is proved to be the key factor in membrane stability and hence extraction efficiency. The study reports the case study on use of ultrasound for membrane preparation and extraction efficiency. Overall the methodologies for preparation of liquid emulsion membranes and membrane stability are found to have great potential in the field of waste water treatments.

“…Generally, increasing V int /V m decreases the emulsion stability. Kumbasar and co-worker [69][70][71][72][73] reported that increasing the stripping solution volume made the emulsion unstable and there was leakage of stripping solution into the feed solution, due to an increase of the emulsion viscosity and also an increase of the internal droplets diameter. Increase in droplet diameter decreases the interfacial contact area between the emulsion and the continuous phase and thereby decreases the percentage extraction of metal [24,49].…”

“…The emulsion liquid membrane (ELM) was invented by Li (1968) and is known as one of the most promising separation methods for trace extraction of metal contaminants (Kumbasar and Sahin, 2008;Chakraborty et al, 2003;Ortiz et al, 2003;Biscaia Junior et al, 2001;Ferraz et al, 2007) and hydrocarbons (Correia and de Carvalho, 2003;Park et al, 2006) owing to the high mass transfer rate, high selectively, low solvent inventory and low equipment cost. Frankenfeld et al (1981) reported that the ELM could be up to 40% cheaper than other solvent extraction methods.…”

-Nano-assisted inclusion separation of alkali metals from basic solutions was reported by an inclusion-facilitated emulsion liquid membrane process. The novelty of this study is application of nanobaskets of calixcrown in the selective and efficient separation of alkali metals as both the carrier and the surfactant. For this purpose, two diacids, p-tert-butylcalix [4]arene-1,2-crown-3 in the cone and the 1,2-alternate conformation, as well as another diacid, p-tert-butylcalix[4]arene-1,2-thiacrown-3 in the cone conformation, were synthesized. Their inclusion-extraction parameters were optimized, including the calixcrown scaffold (04, 4 wt%) as the carrier/demulsifier, commercial kerosene as the diluent in the membrane, sulphonic acid (0.2 M) and ammonium carbonate (0.4 M) as the strip and the feed phases; the phase and the treat ratios were 0.8 and 0.3, mixing speed (300 rpm), and initial solute concentration (100 mg/L). The selectivity of the membrane was examined for more than ten interfering cations was examined and the results reveled that, under the optimized operating condition, the degree of inclusion-extraction of alkali metals was as high as 98-99%.
