“…Separation and recovery of copper [14][15][16][17][18], zinc [19][20][21], nickel [22][23][24], alkali metals [25], precious metals [26][27][28][29], rare earth metals [30][31][32][33][34], etc., from aqueous technological solutions and wastewater purification based on supported liquid membranes has intensively been studied. One of the problems is that when H + concentration difference is used as a driving factor to transfer metal ions, with time this difference decreases and the process stops.…”

“…More recently, analytical expressions for the transport of three species in the membrane phase have been established (Kanungo and Mohapatra, 1995a). Competitive reaction schemes in which two or more metal ions react with a given extractant have been treated with the numerical methods indicated above (Juang, 1993a;Juang and Liang, 1993b) or by considering only the diffusion in the membrane phase as the principal resistance. In the latter case, this approach can be used in the reported systems because transport limited by the kinetics is essentially never observed when using crown ethers as carriers (Fyles, 1991).…”

Carrier-mediated transport through supported liquid membranes is currently recognized as a potentially valuable technology for selective separation and concentration of toxic and valuable metal ions. In this paper, a review of the fundamental aspects concerning metal ion transport and the influencing factors are surveyed in terms of data modeling, membrane efficiency (permeability, selectivity, stability), and data acquisition and evaluation. An account of the information reviewed demonstrates the need for critical reflection on system performances in order to accomplish scaling up operations. On the same basis, an attempt to outline some future trends in the field is presented.

“…In the past 20 years, non-dispersive solvent extraction has been used to avoid many of the shortcomings associated with the SX as described above (Juang and Liang, 1993;Swain et al, 2004). When a microporous membrane is impregnated with a fluid that wets the membrane, the fluid fills the pores of the membrane.…”

Separation of zinc and lead from an aqueous nitrate medium using supported liquid membrane with di(2-ethylhexyl)phosphoric acid (D2EHPA) as mobile carrier was studied. Celgard-2500, a microporous polypropylene film, was used as the solid support for the liquid membrane with a plate and frame type of cell used for the experiments. The effects of different parameters such as pH of feed solution (1-3?5), D2EHPA concentration in the membrane phase (10-100 mol m 23 ), acid concentration in strip solution and flowrate of the aqueous solution on separation of lead and zinc were studied. It was observed that zinc flux across the membrane increased with pH of the feed solution up to 3?0 and thereafter decreased while zinc flux increased with the D2EHPA concentration in the membrane phase up to 75 mol m 23 and thereafter decreased. The flowrate of 100 mL min 21 was sufficient to reduce the resistances due to the aqueous boundary layer while 950 mol m 23 H 2 SO 4 was found sufficient to strip the metals from the membrane phase in the strip phase. Under the study conditions, the copermeation of lead with zinc was observed to be negligible.
