“…These results indicated that the diffusion of the metal-carrier complex is more important in deciding transport rates as compared to the D U values. This also suggests that the transport is a diffusion controlled process similar to other SLM systems studied earlier [19][20][21].…”

“…For the U-TODGA transport system, the effect of carrier concentration on the P value was studied up to 0.2 M TODGA and a saturation effect was seen [21]. On the other hand, a peak value at 0.10 M TODGA was reported for both trivalent (Am(III)) and tetra-valent (Th(IV)) actinide ions [20,28]. However, for the Am-T2EHDGA transport system, the transport behaviour was similar to the present system [19].…”

“…The micro porous membrane filter (0.45 micron pore size) was soaked in the carrier solution (usually 0.2 M T2EHDGA in n-dodecane, containing 30% iso-decanol as the phase modifier) for 10 min prior to use [20]. Subsequently, the membrane was removed from the solution and wiped carefully with a tissue paper to remove the excess fluid.…”

“…Supported liquid membrane studies have revealed that the transport rate of Am(III) using TODGA as the carrier were comparable to that with T2EHDGA [19,20]. Though U transport rate is lower as compared to Am(III) with TODGA, it was of interest to study the transport behaviour for understanding the possible interference during the recovery of minor actinides from HLW with TODGA as the carrier extractant.…”

Liquid membranes (LMs) constitute an emerging technique that can be used as an alternative for separation processes, mainly due to their high efficiency, and as such are being looked into for industrial applications. This article provides information on two types of LMs, supported liquid membrane (SLM) and emulsion liquid membrane (ELM), presenting the principles, methods of preparation, transport mechanisms, stability, and applications of a number of separation processes. SLMs use porous supports impregnated with a solvent. Solute molecules dissolve into the membrane at the feed/membrane interface, and the dissolved species diffuse through the membrane and desorb at the receiving phase. Numerous processes based on SLMs have been proposed as effective methods for the separation of different chemical species, such as organic compounds, metal ions, gas mixtures, or pharmaceutical compounds. Nevertheless, the application of SLMs on a large scale is still limited due to inadequate membrane stability. Much effort has been put into to improve SLM stability, and one possible alternative is to substitute organic solvents in the membrane by room temperature organic liquids (ILs), which possess unique properties that are interesting in the context of LMs. Thus, supported ionic liquid membranes (SILMs) receive special attention in this article. ELMs are prepared by the intensive mixing of two nonmiscible phases (e.g., water droplets in an oil phase) and the addition of some strong surfactant. Some recent advances in this field are presented.
