Standard Entropy of Adsorption

Interfacial tensiometry as a novel methodology for the determination of surfactant adsorption at a liquid surface

“…1 illustrates the dynamic surface tensions measured for the C 13 DMPO solutions using the drop-shape method. Adsorption equilibrium in the drop is achieved after approximately 10,000 s. This is in agreement with dynamic surface tensions calculated from the Ward and Tordai equation [7] with an additional term approximately accounting for the surface curvature [3]:…”

Equilibrium and dynamic surface properties of trisiloxane aqueous solutions. Part 2. Theory and comparison with experiment

“…The dynamic of adsorption is described by well-known integro-differential equation derived by Ward and Tordai [24]. This equation gives a relationship between the dynamic adsorption, Γ(t), and the subsurface concentration c(0,t) for a fresh non-deformed surfaces:…”

On the Adsorption of Octanoic Acid at the Mercury/Electrolyte and Air/Water Interfaces

“…From our experiments by (22,23) it is possible to directly access the values C 0 , C S , and C to M KCl and 5 1 10 03 M HCl, and s e is the equilibrium The equilibrium surface tension vs concentration isotherm surface tension of the octanoic acid solution. From the reof octanoic acid was experimentally determined.…”
