Article abstract of DOI:10.1002/hlca.19800630121

The dioxa-dithioamide 3 behaves as a highly selective ionophore for Cd(2+) in solvent polymeric membranes.It induces cation-permselectivity in these membranes with a transference number of 1 for Cd(NO3)2- and of 2 for CdCl2-solutions.In the presence of a proton carrier, 3 may be used to selectively pump Cd(2+) through membranes by coupling with a pH gradient.
