abstract = "Permselective ion transport at the surface of poly(vinyl chloride) supported neutral carrier liquid membranes, contacted with solutions of different kinds of metal salts was investigated by FTIR-ATR spectroscopy. When the PVC supported membranes containing dibenzo-18-crown-6 and bis[(benzo-15-crown-5)-4′-methyl] pimelate respectively were contacted with KCl aqueous solution, selective transport of K+ ions into the interfacial region of the membrane was evidenced by the change in IR spectra through complexation of K+ ions with neutral carriers. The cation permselectivity was correlated with almost zero extractability of liquid/liquid extraction of the corresponding bulk solvent extraction systems. A general empirical relation between potentiometric response slopes of liquid membranes and extractability of metal salts in a series of bulk extraction systems was also deduced.",
