Reversible Reduction of Metal Ions on Stationary Electrode

1 Reversible Reduction of Metal Ions on Stationary Electrode 

The parameter A is a hnear funetion of the square-root of frequency but A f[, depends on A only within the interval 0.1 A 10. So, the net peak current A/p depends linearly on if the ehange of frequency does not eause the change of 

This means that the linear relationship between A/p and exists if either A 0.1, or A 10 at all frequeneies [40,42]. 

The voltammograms were calculated by assuming that no metal atoms were initially present in the film. The response depends on the dimensionless film thickness A = T(// )) /2, where L is the real film thickness [40]. Eigure 2.23a shows that the dimensionless net response is the highest if A = 1. This condition is satisfied if, for instance, D = 9x 10 cm /s, / = 100 Hz and L = 3 pm, which is rather thick film. In trace analysis the films are usually much thinner than a micrometer [41]. The maximum net response appears if the film thickness is approximately equal to
