Abstract: The dynamic surface tensions of the aqueous solutions of per-fluorooctanoic acid, sodium dodecylsulfate and diethylene glycol mono-w-octyl ether were measured at different temperatures by the oscillating jet method, respectively.The results show that the surface adsorption of all these systems is diffusion-controlled.
