6.8.5 Voltammetry in Ionic Liquids
When ionic liquids are used as a solvent for the
measurement of the cyclic voltammetry of
organic compounds, the observed redox
currents are generally extremely small. This is
due to the high viscosity of ionic liquids, which
decreases the diffusion coefficient. For instance,
