Determination of the Real Surface Area of a Screen-Printed Electrode by Chronocoulometry

Determination of the Real Surface Area of a Screen-Printed Electrode by Chronocoulometry

A simple and effective method applying chronocoulometry and cyclic voltammetry to the determination of the real surface area of a screen-printed electrode, for the first time, is reported. The method is based on the Anson plot and the standard addition method. This method could greatly facilitate de...

Zusammenfassung:A simple and effective method applying chronocoulometry and cyclic voltammetry to the determination of the real surface area of a screen-printed electrode, for the first time, is reported. The method is based on the Anson plot and the standard addition method. This method could greatly facilitate determination of the real surface area of commercial screen-printed electrodes, which still remains underdeveloped despite the critical importance of quality control in this industry.
