The theory of chronoamperometric current at ring electrode and its experimental verification |
| |
| Abstract: | The equation of a chronoamperometric current at a ring electrode is presented. It is a simple anal. expression which is easily calculated and fit for any radius of ring electrode and any time. To examine the validity of the theory, experimental studies with K4Fe(ON)6 in 0.5 mol/cm3 KCl solution were carried out at the Au micro-ring electrode. The experimental values are in good agreement with the theor. ones. |
