TL;DR: In this article, a kinetic model of the Faradaic processes was developed and found to satisfactorily describe the variation in the steady-state concentration of hydrogen peroxide (H2O2) generated over a range of CDI operating conditions.

TL;DR: The electrode potentials required for the induction of Faradaic reactions were analyzed, providing robust thermodynamic explanations for the occurrence of carbon oxidation at the anode and H2O2 generation at the cathode during the ion adsorption process.

TL;DR: The approach to description of ion removal, at least in batch studies, appears robust and should assist in optimization of design and operating conditions such that optimal removal of trace ionic species is achieved even when high background concentrations of salt are present.

TL;DR: An innovative flow electrode comprising redox-active quinones to enhance the effectiveness of water desalination using flow-electrode capacitive deionization (FCDI) is described and the cycling behavior of the quinoid mediators in the anode flow electrode demonstrated a relatively high stability at the low pH induced, suggesting that the mediator would be suitable for long-term operation.

TL;DR: The relatively simple electrosorption model developed here provided a satisfactory description of both fluoride removal and current evolution and would appear to be a useful tool for prediction of CDI performance over a range of operating conditions, cell arrangements and feed water compositions though scope for model improvement exists.
