Abstract
Surface relaxation processes of liquid solutions, under not-far-from-e quilibrium conditions, are interpreted from a phenomenological point o f view by application of the theory of distributed systems. In the cas e of diffusion-controlled adsorption, exact analytical expressions des cribe the transient responses of bulk concentration and dynamic surfac e tension, consequent to trapezoidal pulses of relative surface area. The mathematical treatment shows that surface responses have a definit e physical significance, as they manifest a constitutive property of t he system, i.e. the surface dilational modulus.
