Opis:: An experimental investigation concerns zinc(II), cobalt(II), nickel(II), copper(II) and cadmium(II) ions separation from aqueous chloride solutions by solvent extraction and transport through polymer inclusion membrane (PIM) processes. The selective transport of metal ions from the aqueous chloride source phase through PIM containing cellulose triacetate (support), o-nitrophenyl pentyl ether (plasticizer) and di(2-ethylhexyl)phosphoric acid (ion carrier) is shown. Zn(II) can be effectively removed from dilute aqueous chloride solutions by its transport through PIMs with di(2-ethylhexyl)phosphoric acid as the ionic carriers into 1.0 M HCl as the receiving phase. The transport selectivity of Zn(II) over Co(II), Ni(II), Cu(II) and Cd(II) decreases while the pH of the solution increases in the source phase. Also, by solvent extraction, Zn(II) can be selectively removed from dilute aqueous chloride solutions.

Cyanex 301
Opis:: The selective transport of zinc(II) and cadmium(II) ions from aqueous chloride or sulfate source phase through polymer inclusion membranes (PIM) containing cellulose triacetate (support), o-nitrophenyl pentyl ether (plasticizer) and di(2,4,4-trimethylpentyl)dithiophosphinic acid - Cyanex 301 (ion carrier) is shown. Zn(II) and Cd(II) ions can be effectively removed from dilute chloride and sulfate aqueous solutions into 1.0 M HCl or H2SO4 as the receiving phase. The separation coefficients were practically constant for acid concentrations in the receiving phase ranging from 0.01 to 1.0 M Copper(II), zinc(II), cadmium(II), cobalt(II), and nickel(II) ions removal from aqueous chloride solutions in transport through PIMs is also shown. These metal ions can be effectively removed from dilute aqueous chloride solutions in transport through PIMs with di(2,4,4-trimethylpentyl)dithiophosphinic acid as the ionic carriers into 1.0 M HCl. The selectivity coefficients of Cu(II) over Zn(II), Cd(II), Co(II) and Ni(II) were low and decreased with an increase in the pH of source aqueous phase.

Opis:: In this study, palladium-modified nickel foam substrate was applied to examine ethanol oxidation reaction (EOR) in 0.1 The transport of cobalt(II), nickel(II), copper(II), and zinc(II) ions from chloride solutions across polymer inclusion membranes (PIMs), which 1-heptylimidazole (1̲) or 1-heptyl-2-methylimidazole (2̲) or 1-heptyl-4-methylimidazole (3̲) as the ion carrier was reported. The steric effect for carriers 2̲&enspand 3̲&enspdecreases the transport of all ions except Cu(II). The initial fluxes of metal ions transport across PIMs with the 1̲- 2̲&enspdecrease in the sequence: Cu(II) > Zn(II) > Co(II) > Ni(II), whereas for 3 they were Cu(II) > Zn(II) > Ni(II) > Co(II). The highest recovery values were obtained for Cu(II), this being 99 and 85% for carrier 1̲&enspand 2̲, respectively. In both membranes the degree of deposition of the Zn(II) ions was comparable. Zn(II), Co(II) and Cd(II) ions, which form complexes with coordination numbers 4 and 6, are more easily recovered with the use of carriers 2̲&enspand 3̲. Ni(II) ions, which form complexes with coordination number 6 only, practically remain in the feeding phase. PIMs with alkylimidazoles were characterized by non-contact atomic force microscopy.
