“…Copper ion is both vital and toxic for many biological systems [10,11]. Copper ion transport has been examined for different carriers [7,10,[12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] but some of them have the drawbacks of a slow rate of transport or a lack of high selectivity and efficiency. Therefore, the development of effective and specific systems for studying transport of metal ions, and in particular Cu(II), is still a challenging task from both the practical and theoretical viewpoints.…”

The transport of Cu 2+ ion through a chloroform bulk liquid membrane containing a new tetradentate Schiff base, 6,6 ′ -Diethoxy-2,2 ′ -[2,2-dimethyl propane-1,3-diylbis (nitrilomethylidyne)]-diphenol (DDPND), as a specific ion carrier was studied. The parameters influencing the transport efficiency such as type and concentration of the stripping agent used as the receiving phase, pH and ammonia concentration in the source phase, carrier concentration in the membrane, membrane solvent type and time dependency of the process were studied. The selectivity and efficiency of Cu 2+ transport from aqueous solutions containing other cations such as Zn 2+ , Pb 2+ , Cd 2+ , Co 2+ , Ni 2+ , Ca 2+ , Mn 2+ , Fe 3+ and Hg 2+ ions were investigated. The interfering effect of Pb 2+ and Cd 2+ ions was considerably diminished in the presence of ammonium acetate as a proper masking agent in the source phase. The amount of copper transport through the liquid membrane after 2 h was 91.7 ± 1.3%. The applicability of the method was checked for the separation of copper ions from soil sample.

DC potential-reinforced bulk-liquid membrane transport (PR-BLMT) was studied using Fe (II)-1,10-phenanthroline complex (Fe-Phen) as a model, for the first time. Indeed, this electro-enhanced ion transport study was performed by combination of the electro-membrane extraction (EME) and bulkliquid membrane transport (BLMT). Iron (II) ions were transported from 3 mL aqueous solution (pH=4.3) into 1.5 mL of 1.0 M HNO 3 solution through 12 mL dichloromethane containing 5×10 -3 M 1,10-phenanthroline. Ion transport was significantly improved by applying a DC voltage within the transport process. To maximize the transport, the important experimental variables including pH and volumes of donor and acceptor phases, ionic strength, type and volume of BLM, extraction time, DC potential, and type of electrode were studied. The results showed that exhaustive transport of Fe (II) ions through organic membrane was possible in the range of 0.2-27 µg mL -1 (R 2 =0.998) with a relative standard deviation (RSD) of 3.5% (n=8). The applicability of the proposed PR-BLMT method to interfering matrices was evaluated by successful transport of Fe (II) ions in different real water samples.
