Abstract

This paper focuses on the characterization of an electrochemical flow cell designed for capacitive desalination, by using the FeIII(CN)63−/FeII(CN)64− redox couple as an electrochemical probe. A relationship between the potential scan rate and the electrolyte flow rate has been first established by defining a dimensionless number, θ. Depending on the θ values, two regime domains – dependent and non-dependent from the flow rate - have been defined. The dimensionless number θ was found to be of great help for defining the suitable flow rate for several carbon based electrodes exhibiting different surface area, using FeIII(CN)63−/FeII(CN)64− redox couple as an electrochemical probe. The proposed electrochemical analysis is a way to optimize the performance of an electrochemical flow cell for capacitive desalination applications.
