Submonolayer injections

Submonolayer Injections of Surfactants. Plots of surface pressure vs. time are shown in Figure 2. Time zero is the time at which the injection was completed. The surface pressure, initially 5 dynes/cm, rises sharply and subsequently decreases with time to an equilibrium value. The equilibrium surface pressure and potential change are summarized in Columns 2 and 3 of Table I. A nonlinear relationship exists between the log of the difference of the equilibrium pressure, 7re, the pressure at time t, 7Tt, and time [i.e., log (7re—tt ) vs. t the surface pressure change is therefore not a first-order phenomenon.
