Dynamic Surface Tension of Micellar Triton X-100 Solutions by the Maximum-Bubble-Pressure Method
Journal of Colloid and Interface Science, 1994Abstract The dynamic maximum-bubble-pressure method was used to measure the dynamic surface tension of Triton X-100 solutions (at the CMC and at concentrations above the CMC). Measurements were performed at 30.0, 40.0, 50.0, and 60.0°C. The results at 30.0°C are in excellent agreement with the data obtained through other methods (oscillating jet and ...

Abstract The maximum bubble pressure method for measuring dynamic surface tension is reexamined, using high speed cinematography, particularly with respect to the process of bubble formation and the determination of the true surface age. A method for direct measurement of the time of bubble growth is suggested which readily permits routine ...

Studies of concentrated surfactant solutions using the maximum bubble pressure method
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2000Abstract An analysis of the adsorption process during the deadtime period in maximum bubble pressure experiments is performed. The adsorption dynamics is calculated for the actual surface area increase of a bubble in a surfactant solution, which depends on characteristic system parameters such as the length and diameter of the capillary and the ...

Abstract A newly designed apparatus based on the principle of maximum bubble pressure can be used for measuring the dynamic surface tension in a time interval from 1 ms to 10 s. The surface tension values for pure liquids obtained at small lifetimes are influenced by hydrodynamic effects.

Surfactant solution systems are encountered in many different applications, including as a method to enhance the nucleate boiling performance of water. Characterizing the attendant interfacial phenomena requires precise predictions of their surface tension relaxation behavior.

Abstract Industrial processes frequently use surfactants to lower liquid surface tension and promote wetting. In many instances, it is incorrect to apply the equilibrium (static) surface tension to predict the behavior of these processes because they operate under time-dependent (dynamic) conditions.

Abstract A method is presented for the use of the maximum bubble pressure method of measuring surface tension, to measure dynamic surface tensions of solutions of slowly diffusing soluble molecules. Data obtained using this method on aqueous solutions of decanoic acid and decyl alcohol are also presented.

Abstract In the measurements of the time dependency of the surface tension (γ) by the maximum bubble pressure method, the effective age of the surface of the solution (T) is smaller than the measured interval between the separation of the two subsequent bubbles (t).

Dynamic surface tension of micellar solutions studied by the maximum bubble pressure method
Colloid and Polymer Science, 1995A theoretical model for the dynamic surface tension of an air bubble expanding in micellar surfactant solution is proposed. The model accounts for the effect of expansion of the bubble surface during the adsorption of surfactant molecules (monomers) and the effect of disintegration of polydisperse micelles on the surfactant diffusion.
