Ionic transfer

Ionic transfer is a term which can be used to describe the transfer of ions from one liquid phase to another.

This is related to the phase transfer catalysts which are a special type of liquid-liquid extraction which is used in synthetic chemistry.

For instance nitrate anions can be transferred between water and nitrobenzene. One way to observe this is to use a cyclic voltammetry experiment where the liquid-liquid interface is the working electrode. This can be done by placing secondary electrodes in each phase and close to interface each phase has a reference electrode. One phase is attached to a potentiostat^[1] which is set to zero volts, while the other potentiostat is driven with a triangular wave. This experiment is known as a polarised Interface between Two Imisable Electrolyte solution experiment. For examples of its use see the PhD thesis of Laure TOMASZEWSKI at EPFL.^[2]
