V. Vacheva et al., INFLUENCE OF THE CHAIN-LENGTH ON THE ADSORPTION PARAMETERS OF FATTY ALCOHOLS ESTIMATED ON THE BASIS OF DIFFERENTIAL CAPACITY DATA, Electrochimica acta, 42(15), 1997, pp. 2327-2332
Two analytical models of differential capacity and nonlinear regressio
n analysis have been applied for the precise estimation of the paramet
ers of adsorption of fatty alcohols in the order from butanol to hexan
ol on mercury electrode. One of the models was based on the adsorption
isotherm for a two-component system, and the other used Frumkin isoth
erm with a linear dependence of the interaction parameter on electrode
potential. The ability of both models to adequately predict investiga
ted experimental results is discussed. The obtained precise estimates
of the adsorption parameters of fatty alcohols have been compared and
discussed as well. (C) 1997 Elsevier Science Ltd.
