Computer simulations of cyclic voltammetry experiments at liquid \ liquid interfaces are presented for the transfer of ions (Mz +) assisted by z charged ligands (L-). The main difference, when compared with neutral ligands, is that in the case presented here, all the complexes formed have a different charge and the flux of the ligands has to be taken into account in the definition of the current, in addition to that of the metal ion and those of the (z - 1) charged complexes (the complex with the highest stoichiometry being neutral). The particular cases of M+/L- and M2+/L- systems are presented. The effect, on the cyclic voltammetry response, of various parameters such as association constants, metal and ligand concentration, is analysed and results are compared to the case of neutral ionophores.
