Abstract The diffusion equation was solved and the dynamic surface adsorption Γ(t),which was always used to describe the adsorption at air/solution interfaces,was derived.Two cases of adsorption,i.e. the short time limit and the long time limit,were mainly discussed.As an example,surfactant C_(12)E_7 was chosen and the equilibria and the dynamic surface tensions of its aqueous solution at 25 ℃ were measured.It was proved that for the short time limit the whole process was controlled only by diffusion,however,within the long time range a mixed diffusion-adsorption controlled process appeared.
