“…In the supported liquid membranes, the organic liquid membrane is sandwiched between the aqueous feed and stripping solutions, which move on opposite sides of a porous polymer impregnated with the organic liquid membrane [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ]. In all cases, the mass transfer occurs between the two aqueous phases through the immiscible organic membrane phase.…”

This article is devoted to a brief review of the modelling of liquid membrane separation methods, such as emulsion, supported liquid membranes, film pertraction, and three-phase and multi-phase extraction. Mathematical models and comparative analyses of liquid membrane separations with different flow modes of contacting liquid phases are presented. A comparison of the processes of conventional and liquid membrane separations is carried out under the following assumptions: mass transfer is described by the traditional mass transfer equation; the equilibrium distribution coefficients of a component passing from one of the phases to another are constant. It is shown that, from the point of view of mass transfer driving forces, emulsion and film pertraction liquid membrane methods have advantages over the conventional conjugated extraction stripping method, when the mass-transfer efficiency of the extraction stage is significantly higher than the efficiency of the stripping stage. The comparison of the supported liquid membrane with conjugated extraction stripping showed that when mass-transfer rates on the extraction and stripping sides are different, the liquid membrane method is more efficient, while when they are equal to each other, both processes demonstrate the same results. The advantages and disadvantages of liquid membrane methods are discussed. The main disadvantages of liquid membrane methods—low throughput and complexity—can be overcome by using modified solvent extraction equipment to carry out liquid membrane separations.

“…In 1990, it was claimed that several investigations on SLMs and hollow fiber supported liquid membranes (HFSLMs) had been carried out related to analytical significance of the technique employed for identifying precious and heavy metals . Over the years, tremendous progress in gas separation studies using membranes has been made toward membrane fabrication, improving chemical and physical properties of membrane, process design, and module configuration. ,− In recent years, there has been increasing interest in using SLMs for separation of emerging contaminants, such as pharmaceuticals, and personal care products, as well as recovery of valuable metals from industrial wastewater . Overall, the history of SLMs is characterized by continuous development and innovation, with researchers exploring new applications and optimizing membrane performance to meet the evolving needs of separation and purification processes.…”

The idea of establishing faster/facilitated transport through liquid membranes (LMs) is both theoretically fascinating and promising for applications. One of the most selective, along with lots of desirable promising forms of LMs, is supported liquid membranes (SLMs). Since the introduction of the idea of SLMs a few decades ago, research activities in this sector have been continuously increased. Through a comprehensive analysis of the current state of the art, this review demonstrates the design and application considerations that must be made when determining whether to employ polymeric or ceramic supports in SLMs for gas separation. Following a thorough analysis of the principles of LMs, including their chronology, transport mechanism, and advantages and disadvantages are presented. The various configurations suggested up to date, their road from the laboratory to practical implementation, and their performance are discussed. Finally, potential challenges and opportunities are outlined.
