“…adsorption is diffusion-controlled (7, 8, 10, 12, 13, 16, 17, When we compare the dynamic studies in (9) and (17) seconds the potential does not change for solutions of propa-into n thin layers), A is the surface area, m i is the chemical potential of component i, and s is the surface tension of the nol, butanol, and hexanol. This result was explained by a diffusion model in (28) while in (17) an alternative model surface layer in equilibrium with the subsurface, was developed which considered a simultaneous increase of adsorbed alcohol molecules and a decrease in the dipole…”
