Adsorption of Isobutyramide at the Mercury/Aqueous Sodium Fluoride Solution Interface

摘要

The differential capacity of the electrode/solution interface was measured at constant concentration of NaF (0.25 m) for iso-butyramide concentrations in the range 0.01 to 1 m. The capacity curves were typical of those with moderately strong organic adsorption with a deep shallow minimum negative of the p.z.c. and desorption peaks at extreme positive and negative potentials. Analysis of these data demonstrates that reorientation of the adsorbed amide molecule plays an important role in determining the characteristics of the adsorption isotherm. (JES)
