The Pseudo-Protic Ionic Liquids TOAH⁺Cl^- and TODAH⁺Cl^- as Carriers for Facilitated Transport of In(III) from HCl Solutions

Abstract

The behaviour of the pseudo-protic ionic liquids TOAH+Cl- and TODAH+Cl- in the facilitated transport of indium(III) from HCl solutions is described. Metal transport is investigated as a function of different variables: hydrodynamic conditions, HCl concentration in the feed phase and indium and carrier concentrations. The experimental data are used to model both transport systems and to estimate diffusional parameters associated to them.
