Chronoamperometry is an electrochemical technique used to study the kinetics of electron transfer reactions at an electrode surface. It measures the current flowing through an electrochemical cell as a function of time while holding the potential of the working electrode constant. This allows for the determination of important parameters like the rate constant of the electron transfer reaction, the diffusion coefficient of the analyte, and the concentration of the analyte.
Applications include:
- Studying the kinetics of electron transfer reactions
- Measuring the diffusion coefficient of species in solution
- Determining the concentration of analytes in solution
- Investigating the mechanism of electrochemical reactions
- Characterizing electrode materials
