Chronamperometry
WebChronoamperometry lends itself well to the accurate measurement of electrode area (A) by use of a well-defined redox couple (known n, C 0, and D 0 ). With a known electrode … WebChronoamperometry is the technique in which the current is measured, at a fixed potential, at different times since the start of polarisation. Chronoamperometry is typically carried out in unstirred solution and at the fixed electrode, i.e., under experimental conditions avoiding convection as the mass transfer to the electrode.

WebJan 1, 2016 · Chronoamperometry is a time-dependent technique where a square-wave potential is applied to the working electrode. The current of the electrode, measured as a function of time, fluctuates according to the diffusion of an analyte from the bulk solution toward the sensor surface. Chronoamperometry can therefore be used to measure … WebHence, chronocoulometry is preferred over chronoamperometry for the measurement of electrode area (A) and diffusion coefficients (D). The enhanced signal observed in chronocoulometry also makes it the better technique for measurement of the kinetics of chemical reactions following electron transfer.
