N,N,N′,N′ ‐Tetrabutyl‐3,6‐dioxaoctane‐dithioamide, an Ionophore with Selectivity for Cd 2+ 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(NO 3 ) 2 ‐ and of 2 for CdCl 2 ‐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.
