Dynamic surface tensions and dynamic surface potentials

Adsorption Kinetics of Short-Chain Alcohols at the Water/Air Interface: Diffusion-Controlled Adsorption under the Conditions of a Nonequilibrium Surface Layer

“…These findings are not in conflict dynamic surface tension and dynamic surface potential of with the results of other authors (2,10,14,17,30). Close aqueous alcohol solutions have been published (1-21).…”

“…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…”

“…tions were used as model systems for the elaboration of At short adsorption times the situation is different. It can be new theories (12, 16-20, 25, 27) and novel experimental described by simple approximations derived from the genmethods (9,10,(15)(16)(17)(18)(19).…”

“…For octanol and nonanol a pure diffusion was obtained without taking into account dipole relaxations (17).…”

“…

nol, pentanol) follows a kinetic-controlled mechanism (2, Dynamic surface tensions of short-chain alcohols at very short 10, 14) which allows us to determine so-called adsorption adsorption times were measured by using the maximum bubble rate constants (10,12,14,17,30). The results for the interpressure instrument MPT1 with a modified measuring cell.
