An Interactive Reverse-Engineering Cyclic Voltammetry for Electrochemical ?Systems ?

Cyclic voltammetry (CV) is one of the electrochemical methods that can be used to determine the thermodynamic behavior and response of elements in eutectic salt melts. Through this experimental method, the diffusion coefficients, apparent standard potentials, transfer coefficient, and other parameters can be determined. This work focuses on developing a reverse engineering design of the CV method to help understanding and improving detection techniques. The current approach is analyzing and reconstructing the CV plots for uranium (U) in a LiCl-KCl eutectic salt at different concentration conditions and scan rates. The experimental CV plots used in this work were obtained from previous electrochemical studies. A systematic method and computational code have been developed by using electrochemical fundamentals coupling with various available variables such as the diffusion coefficients, apparent standard potentials, anodic/cathodic peak current and anodic/cathodic peak potential for reverse engineering of the CV technique. Simulated results provide the current (amp) versus potential (V) graphs under different specified conditions showing that this developed method can be used to detect the cathodic and anodic peaks at the reversible and irreversible parts, especially tracing the CV on the cathodic side. In addition, it gives a good view of concentration of each species at cathodic and anodic reactions at different times.
