Title
Adsorption-kinetics with surface dilatation : 3. adsorption to a surface expanded with a constant dilatation rate
Author
Abstract
A theory for the adsorption of a surfactant at the air/water interface, when the surface is expanded with a constant dilatation rate dln OMEGA/dt (OMEGA being the area), is presented. In order to verify the theory, two kinds of experiments were performed: (i) expanding the surface with a constant dilatation rate (area changes logarithmically), while measuring the surface tension as a function of time and (ii) expanding the surface by drawing a strip into the solution, while monitoring the surface tension with time. It is shown that not only the steady state surface tension (sigma for t --> infinity), contains valuable information, but also the transient surface tensions, which give additional information about the process that is going on, or at least confirm the results obtained from the steady state surface tension results only.
