Abstract
By means of maximal bubble pressure method, the dynamic surface tensions of aqueous octanoyl-N-methylglucamine (Mega-8) solutions at 25°C were measured. On the base of the experimental data, the adsorption kinetics of Mega-8 at air/solution interface was studied. In the short time range, the adsorption was diffusion-controlled and the diffusion coefficient was calculated. However, for the long time limit there was an adsorption barrier and the mixed diffusion-activation mechanism was proved.
