Cyclic voltametric methods

The theory for cyclic voltametric methods has not been worked out quantitatively. In his discussion, Delahay indicated that the initial concentration of reacting species will vary from one cycle to another and the initial conditions for the boundary value problem cannot be easily stated. As a result the experimental peak currents should not necessarily be in agreement with derived theoretical values. Delahay concluded that compared with conventional voltametry, voltametry with continuously changing potential has several disadvantages which limit its usefulness. ... 

Current-potential curves have been determined only by the cyclic voltametric method using a sweep rate of 40 mV/sec (cf. Figure 15). ° In the anodic sweep, practically no current flows from 0.4 to 0.9 V. At 0.91 V a vertical rise of the current is observed, and from 0.91 V to 1.6 V the current decreases linearly with potential. The current observed at 0.91 V was dependent on stirring rate...
