Surface tension gradients from surfactant concentration change

Dynamic surface tension is the measure of change of surface tension with time when a new surface is created. It is related to how fast the surfactant molecules diffuse from the bulk solution to the new air—solution interface and is, thus, affected by the concentration gradient near the surface. Dynamic surface tension can give information on the rate of adsorption at the interfece. Dynamic surface tension is related to the equilibrium surface tension (yeq), the concentration (C), and the diffusion coefficient (D) of the surfactant and is approximated by the following equation [49] ... [Pg.152]
