Investigation of Carrier-mediated Anion Co-transport through Organic Membranes by Competitive Transport Experiments

Abstract

Competitive carrier-mediated co-extraction and co-transport of a variety of anions and their counter ions into an organic phase or through supported liquid hydrophobic membranes from aqueous mixtures of salts have been monitored by ion chromatography. The method enables rapid screening of the anion co-transport or co-extraction ability of new potential ionophores and carrier molecules.
