Overshoot and oscillation in surface tension of gelatin solutions.
The experimental data of the surface tension of aqueous gelatin solution reported by Sato and Ueberreiter [H. Sato, K. Ueberreiter, Macromol. Chem. 180 (1979) 829; H. Sato, K. Ueberreiter, Macromol. Chem. 180 (1979) 1107; H. Sato, K. Ueberreiter, ACS Polym. Preprints 20 (1979) 907] were analyzed with a theory of adsorption kinetics with time delay. It is found that the observed overshoot and oscillation of the surface tension are well explained by the present theory. The delay time and the rate constants of adsorption and desorption of gelatin molecules onto the air/gelatin solution interface have been evaluated.
