Sodium‐dicyclohexyl‐ 18‐crown‐6 complex cation was used as carrier for the uphill transport of zinc as Zn(SCN) 4 2− complex anion. By using L‐cysteine as a metal ion acceptor in the receiving phase at the optimized pH of 7.6, the amount of zinc transport through the liquid membrane after 90 min was 97.2 ± 1.0%. The selectivity and efficiency of zinc transport from aqueous solutions containing equimolar mixtures of Ag + , Cd 2+ Co 2+ , Cu 2+ , Fe 2+ , Ni 2+ , Pb 2+ , Pd 2+ , Sr 2+ , Bi 3+ , Cr 3+ and Fe 3+ ions was investigated. In the presence of NH 2 OH.HCl as a suitable masking agent in the source phase, the interfering effect of Cu 2+ and Pb 2+ ions was diminished drastically.
