Highly Silver Ion-selective Transport Through Liquid Membranes Containing Cyclic and Acyclic Polythiamonoazaalkanes Bearing an Easily Ionizable Moiety

Abstract

Liquid membranes containing cyclic and acyclic tetrathiazaalkanes bearing a hydrazone moiety as a proton-dissociable group exhibited effective uphill silver ion transport behavior in the proton-driven cation transport. Excellent silver ion selectivities relative to other class ab and class b metal ions were observed for these membranes when citric acid was used for adjusting pH and for preventing hydrolysis of several metal ions in the source phase. Complete recovery of silver ion from a silver solder sample was selectively achieved using the liquid membrane containing acyclic tetrathiazaalkane hydrazone.
