Abstract

Based on the Nelder-Mead simplex technique, a program for the regression analysis of electrocapillary curves (ECC), which is aimed at determination of adsorption parameters of simple organic substances, is developed. This method is tested by the example of theoretically calculated ECC strictly corresponding to the model of two parallel capacitors. Then, the method is used for the regression analysis of ECC on a mercury electrode in 0.916 M NaF solutions with different additions of 5-chlor-1-penthanol. The adsorption parameters found for this system are in a good agreement with those obtained earlier by the regression analysis of differential capacitance curves.
