Half-Wave Potential for the Different Cases

For the different types of assisted-ion-transfer reactions, it is possible to express the half-wave potential as a function of experimental parameters such as the concentration of the ligand or that of the transferring ion. 

the wave for the assisted ion transfer should shift 60/z mV per decade of ligand concentration. In this case, if the assisted ion transfer is fast, the current is controlled by the diffusion of the ligand and that of the complex, both in the organic phase. This is why Equation 1.61 does not depend on the parameter This equation is often used for assisted-proton-transfer reactions where the acidic pH is varied to measure P . 

If the terms of lowest power may be neglected, this equation reduces to 

This method was recently extended by Garcia et al. for different competitive ligands [174].
