Abstract
SEVERAL studies1–3 have examined the concentrative transport4 of ions through bulk liquid membranes. The energy for the transport in these systems is the pH difference—the chemical potential difference of protons across the membrane. We describe here a redox reaction-driven transference system in which picrate anion, a lipophilic anion, moves not only against its concentration gradient but also against its electrochemical potential gradient through bulk organic solvent.
