Chronoamperometry curve
WebChronoamperometry is a conventional approach for analyzing the CaCO 3 scale deposition behavior. In the chronoamperometry test, the potential of −1.2 V (vs SCE) is applied on the 304SS electrode at 25 °C. Fig. 3 shows the chronoamperometry curves of the blank solution obtained for applied potentials of −1.2 V on the 304SS electrode at 25 °C. WebChronoamperometry Purpose. Chronoamperometry is used to study the kinetics of chemical reactions, diffusion processes, and adsorption. In this technique, a potential step is applied to the electrode and the resulting current vs. time is observed. The Physical Electrochemistry Chronoamperometry experiment supports both single- and double …
