“…Removal of phenol was considered as Type 1 facilitation, where the mass transfer rate is increased by incorporating a stripping agent in the internal phase and the stripping agent will react with the solutes to form membrane insoluble product (11,13,21,22,23). However, based on the previous study (12,14), the used of the carrier were also performed in the extraction of phenol. Hence, in this research, palm oil will be utilized as a novel, naturally occurring and green liquid membrane for the recovery of phenol from the aqueous solution.…”

“…Although several studies have been made on the separation of phenols from water by ELM, [6][7][8][9][10][11][12][13][14][15][16][17][18][19] comprehensive studies on the effects of process variables are yet to be carried out. Additionally, little work has been reported in the literature on the stability of the membrane [20] and its reuse.…”

This work aims to the extraction of the priority pollutant 4-nitrophenol (4-NP) from water by emulsion liquid membrane (ELM). Liquid membrane consists of a diluent (hexane) and a surfactant (Span 80). Sodium carbonate solution was used as internal aqueous phase. Effects of important experimental conditions governing the stability of the W/O emulsion were investigated. Influence of operating parameters that affects the permeation of 4-NP such as surfactant concentration, emulsification time, sulfuric acid concentration in external phase, acid type in external phase, internal phase concentration, type of internal phase, stirring speed, volume ratio of internal phase to membrane phase, treatment ratio, 4-NP initial concentration, and diluent type was examined. This study also evaluated the effect of Na 2 CO 3 concentration in the internal aqueous phase on the stripping of 4-NP. Additionally, the reuse of the recovered membrane was studied. Under most favorable conditions, practically all the 4-NP and aniline (AN) molecules present in the feed phase were extracted. The recovery of the membrane phase was total and the extraction of 4-NP was not decreased. The ELM treatment process represents a very interesting advanced separation process for the removal of 4-NP and AN from aqueous solutions.

“…Ng et al studied the percentage removal of phenol from aqueous solution by emulsion liquid membrane and emulsion Leakage. [15] Various parameters such as membrane: external phase ratio, membrane: internal phase ratio, emulsification speed, emulsification time, carrier concentration, surfactant concentration and internal phase concentration. These all parameters effect the percentage removal of phenol and emulsion leakage.…”

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.
