A comparison of the analytical utility of three different potential ramp techniques in voltammetry, using a carbon-paste electrode

Electrochemical Investigation of Resorcinol in Pterocarpus marsupium RoxB by Cyclic Voltammetric Study

“…On substitution of the diffusion-coefficient value (12.2 × 10 6 cm s-1 ) in the following equation: i p = (2.69 × 10 5 ) n 3/2 D 1/2 υ 1/2 C o where i p is the peak current, n is the stoichiometric number of electrons involved in the electrode reaction, A is the area of electrode in cm 2 , D o is the diffusion coefficient of (cm 2 s -1 ), C o is the concentration (mol/cm 3 ) and υ is the scan rate in (Vs -1 ). Based on the above equation the surface area of the electrode was found to be 0.0287 cm 2 [14][15][16][17][18].…”
