Classical electrochemical approaches were evaluated for investigating the basic properties of deep eutectic solvents (DES) with a special focus on the mass transport phenomena and diffusion of charged species in DES. Three classical DES were considered: Reline, Ethaline and cholinechloride-lactic acid mixture. Cyclic voltammetries of the ferrocene oxidation and of the ferricyanide reduction, respectively with charge 0 and -3, exhibit well-defined responses in these media. For all considered DES and redox molecules, diffusion processes govern the masstransport of the redox molecules from the solution to the electrode. Derived diffusion coefficients were extracted and found to present some inconstancies with the classical StokesEinstein law for homogeneous media. The diffusion coefficients were found to be almost unaffected by the charge present on the diffusing molecules contrarily to observations made for ionic liquids.
