Development and construction of an electrochemical measuring method for in-situ analysis of molten salt for use in solar power plants

Abstract

The objective of this work was to construct and develop an electrochemical monitoring method for the in-situ analysis of impurity ions in molten solar salt. In the experiments shown above, different impurities were added to the molten salt, electrochemical experiments were performed by cyclic voltammetry and the peaks corresponding to each impurity were monitored. The potential represents the position of the peak and the current represents the height of the peak. The chemical reactions present were inferred and the relationship between the peak height and concentration correspondence was obtained. The diffusion coefficients were calculated and error analysis was performed.
