Abstract

The active transport of silver ions through a supported liquid membrane (SLM) containing bathocuproine (4,7-diphenyl-2,9-dimethyl-l,10-phenanthroline) as a carrier was investigated under various experimental conditions. The magnitude of the permeation velocity of metallic ions through the SLM was in the order Ag⁺ > Cd²⁺ ≫ Zn²⁺ > Cu²⁺ when nitrite ion was used as the pairing ion species that is cotrans-ported with metallic ion. The permeation velocity of silver(I) ions through an SLM was dependent on the concentrations of the silver ion, bathocuproine, and nitrite ion. An equation for the transport of silver ions, consisting of three important factors, i.e., the concentrations of metallic ion, carrier, and pairing ion species, was derived.
