Highly efficient and selective membrane transport of silver(I) using 15-crown-5 as a selective ion carrier

Selective transport of Ag⁺ cation through a nitrobenzene bulk liquid membrane with 15-crown-5 as an efficient carrier was studied. The maximum transport value of 88.02 ± 0.78% was observed for Ag⁺ ion after 8 h at Ag⁺ concentration of 4 × 10^?4 M. The selectivity and efficiency of Ag⁺ cation transport from aqueous solutions containing equimolar amounts of Cr³⁺, Co²⁺, Ni²⁺, Zn²⁺, Cd²⁺, and Pb²⁺ cations were also investigated.
