| Abstract: | N,N,N′,N′-Tetrabutyl-3,6-dioxaoctane-dithioamide, an Ionophore with Selectivity for Cd2+ The dioxa-dithioamide 3 behaves as a highly selective ionophore for Cd2+ 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 Cd2+ through membranes by coupling with a pH gradient. |
