“…Supported liquid membrane (SLM) technology has recently received considerable attention as an alternative to conventional solvent extraction. The technology offers a number of advantages such as low energy consumption, minimal capital investment and operating cost, simple operation, easy scale up, and simultaneous extraction and stripping in a single step, among others [13].…”

“…It has the advantage of non‐equilibrium mass transfer, where the solute can move from a low to high concentration solution . The other advantages of this technique are the minimal amount of carrier needed and the fact that extraction and stripping steps are combined into a single step . Recently, the supported liquid membrane has attracted particular attention in the field of metal separation because in comparison with conventional solvent extraction, constraints such as emulsification, flooding, loss of solvent, phase disengagement, and large solvent inventory could be avoided .…”

In this study, the extraction of europium from nitric acid solution by a flat sheet supported liquid membrane using Cyanex272 as a carrier was investigated. The influence of effective parameters on the extraction of Eu was studied and the optimum conditions were derived. Then a theoretical model was developed for unsteady‐state transport of Eu ions through the supported liquid membrane. In this model, the variation of carrier concentration in the membrane phase was taken into account. The partial and complete differential equations obtained for the feed, membrane, and stripping phases were numerically solved and the results were compared with the experimental data. The verified model was used to simulate the concentration distribution of the metal‐carrier complex and carrier as a function of position and time in the membrane phase. Using the results of numerical solution, the derived equations were also solved analytically.

“…Other synergistic effect was observed between Cyanex272 and TBP for the separation of yttrium ions from rare earths mixture in a microporous hydrophobic hollow fiber supported liquid membrane 42 . Zaheri et al 6 studied the combination of 070001-3 D2EHPA and Cyanex272 for separation of Eu from Dy. The paired extractant showed good selectivity for Eu and good long term stability.…”

Abstract. The chemical, catalytic, electrical, magnetic, and optical properties of rare earth elements are required in broad applications. Rare earth elements have similar physical and chemical properties thus it is difficult to separate one from each other. Rare earth element is relatively abundant in earth's crust but rarely occur in high concentrated deposits. Traditionally, ion-exchange and solvent extraction techniques have been developed to separate and purify single rare earth solutions or compounds. Recently, membrane starts to gain attention for rare earth separation by combining membrane and proven technologies such as solvent extraction. Membrane-based process offers selective, reliable, energy efficient and easy to scale up separation. During membrane-based separation process, one phase passes through membrane pores while the other phase is rejected. There is no direct mixing of two phases thus the solvent loss is very low. Membrane can also lower solvent physical properties requirement (viscosity, density) and backmixing, eliminate flooding phenomenon and provide large interfacial area for mass transfer. This paper will summarize research efforts in developing membrane technology for rare earth element separation. Special attention will be given to solvent extraction related process as the commonly used method for rare earth element separation. Furthermore, membrane configuration and its potentials will also be discussed.
