Adsorption of anionic surfactant at the electrode-NaClO4 solution interface.

Gugała-Fekner D, Nieszporek J, Sieńko D - Monatsh. Chem. (2015)

Bottom Line: At potentials less than -1,200 mV, the adsorption of the anionic surfactant on the electrode does not occur.Low concentrations of the anionic surfactant (below cmc) causes slight changes in the zero charge potential, E z, and the surface tension at this potential, γ z.The adsorption of the anionic surfactant was analyzed using the constants obtained from the following isotherms: Frumkin, corrected Flory-Huggins, and virial.

ABSTRACT

Abstract: Adsorption of 1-decanesulfonic acid at the electrode-NaClO4 solution interface was determined by double-layer differential capacity measurements. At potentials less than -1,200 mV, the adsorption of the anionic surfactant on the electrode does not occur. Low concentrations of the anionic surfactant (below cmc) causes slight changes in the zero charge potential, E z, and the surface tension at this potential, γ z. The adsorption of the anionic surfactant was analyzed using the constants obtained from the following isotherms: Frumkin, corrected Flory-Huggins, and virial.

Fig1: Differential capacity–potential curves of Hg/1 M NaClO4 and various concentrations, as in the figure legend

Mentions: Figure 1 presents differential capacity curves obtained experimentally in 1 M NaClO4 (a) and in a chosen concentration. By introducing to the supporting electrolyte a distinct decrease in differential capacity was caused from −100 to −900 mV. At higher concentrations, a desorption peak is obtained at −1,000 mV. At potentials less than −1,200 mV, the adsorption of the anionic surfactant on the electrode does not occur.Fig. 1
