Chronoamperometry curve
WebJan 1, 2014 · Chronopotentiometry is a controlled-current technique in which the potential variation with time ( t) is measured following a current step. Other current perturbations such as linear, cyclic, or current reversals are also used [ 1, 3, 4, 12 ]. 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 …
