Adsorption dynamics of surfactants at the air/water interface: a critical review of mathematical models, data, and mechanisms
TL;DR: In this paper, a review of equilibrium and dynamic aspects of surface tension and adsorption, primarily of single nonmicellar or premiceller surfactants at the air/water interface, is presented.
Journal ArticleDOI
The analysis of dynamic surface tension of sodium alkyl sulphate solutions, based on asymptotic equations of adsorption kinetic theory
TL;DR: In this paper, the authors derived asymptotic solutions of the adsorption kinetic equations for the liquid phase interface in the regions of infinitely small and infinitely great surface lifetimes (t) for the cases of one and of a few surfactants, on non-deforming and deforming surfaces, under nonstationary, stationary and quasi-stationary conditions.
Journal ArticleDOI
The effects of slightly soluble surfactants on the flow around a spherical bubble
TL;DR: In this paper, the authors investigated the transient evolution of the flow around a spherical bubble rising in a liquid contaminated by a weakly soluble surfactant and showed that a simple relation between the cap angle and the bulk concentration cannot generally be obtained because diffusion from the bulk plays a significant role.
Journal ArticleDOI
Dissolution or growth of soluble spherical oscillating bubbles
TL;DR: In this paper, a new theoretical formulation for mass transport across the dynamic interface associated with a spherical bubble undergoing volume oscillations is presented, where convection-diffusion equations governing transport of dissolved gas in the liquid are written in Lagrangian coordinates to account for the moving domain.
Journal ArticleDOI
Equilibrium and dynamics of adsorption of surfactants at fluid-fluid interfaces
TL;DR: In this paper, a thermodynamic treatment is developed wherein the surface concentration of ionic surfactants is distinguished from their surface excess concentration by the contribution from the electrical double layer.

Time‐Dependence of Boundary Tensions of Solutions I. The Role of Diffusion in Time‐Effects
A. F. H. Ward,L. Tordai +1 more
TL;DR: In this paper, a general theory of diffusion to the surface is derived, which allows for back-diffusion and which makes no special assumptions of a physical nature, and the methods of this theory are applied to analyze recent data on time-effects of short duration.

Dynamic surface tension determination with the maximum bubble pressure method
TL;DR: In this article, the surface tension of surfactant solutions can be observed conveniently as a function of time in the 1- to 100-sec range with some modifications of the normal maximum bubble pressure method.

Diffusion and the kinetics of adsorption of aliphatic acids and alcohols at the water-air interface☆
TL;DR: In this paper, a treatment of adsorption kinetics is presented, which takes explicit account of the diffusion process without presupposing the absence of an adorption barrier, and a new equation suitable for the treatment of experimental data is derived, and its utility is discussed.

On the solution of diffusion controlled adsorption kinetics for any adsorption isotherms
TL;DR: In this paper, the problem of diffusion controlled adsorption kinetics is solved by application of an implicite difference method, which can be used for all forms of adorption isotherms.
