Semi-integrative Voltammetry as an Efficient Tool To Study Simple Electrochemical Systems in Deep Eutectic Solvents.

The utilization of deep eutectic solvents (DESs) in electrochemical studies has grown in recent years due to their low cost and environmental friendliness compared to traditional ionic liquids. However, the determination of diffusion coefficient (D) and heterogeneous constant rate (k) using the traditional electrochemical approach may mask some concerns because of the high viscosity and limited conductivity in these media. In this work, it is shown that the determinations of D and k in glyceline DES by voltammetric studies using the Nicholson approach is problematic.
