- Аннотация: Monte-Carlo method is used for elucidating the effect of a random normally distributed error of capacitance measurements on estimated adsorption parameters of organic substances on an ideally polarizable electrode. Within the model of two parallel capacitors and a Frumkin isotherm with preset adsorption parameters, initial differential capacitance vs. potential dependences are calculated for ten organic-substance concentrations. Then, a random normally distributed error is introduced at every point in these dependences. For estimating the adsorption parameters, 100 series of dependences thus obtained are processed by a nonlinear regression analysis technique. Histograms of distributions of found parameters are plotted. The accuracy of the parameter calculation is assessed for 5 and 10% errors of capacitance measurements. © 2001 MAIK "Nauka/Interperiodica".
