Adsorption behaviour of oxyethylated anionic surfactants 2. Adsorption kinetics
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1998Abstract The adsorption kinetics of anionic surfactants containing one to three oxyethylene groups have been studied at the water/air interface by measuring the dynamic surface tensions using maximum bubble pressure and drop volume tensiometry.

Adsorption of ionic surfactants on charged solids. Adsorption models
Colloids and Surfaces, 1986Abstract A recently proposed model for the adsorption of weak organic electrolytes at a charged solid—aqueous solution interface is briefly reviewed. The implications of using the model to describe surfactant adsorption are discussed. Experimental verification of the model, based on the adsorption results of dodecylammonium bromide on a pyrogenic ...

Cationic surfactants are adsorbed in double layers on low-charged layer silicates. The amount adsorbed is determined by the swelling capacity of the layer silicates and the structure of the cationic surfactant. The swelling ability of the surfactant-layer silicate complex correlates with model concepts assuming densely packed pseudotriple layers ...

Phase Transition Processes in Surfactant Adsorption Layers
Journal of Colloid and Interface Science, 2000Adsorption data in the form of surface tension vs bulk concentration isotherms having strong changes in the slope have often been discussed in the literature in terms of phase transitions in the adsorption layer. It will be shown thermodynamically that these apparent kink points in the isotherms are unreal.

One of the most striking physicochemical characteristics of surfactants is their ability to reduce interfacial tension at low concentration. Surface-active agents are defined by this property. Unlike surfactants, inorganic salts increase the interfacial tension.

Adsorption of surfactants on microbiologies
Chemosphere, 1984Abstract Adsorption isotherms of 5 priority surfactants on microbiologies were obtained. The sources and the conditions of microbiologies were little influenced on the adsorption, except in endogenous state. The employed surfactants were ready to adsorb in the order of AE>APE>LAS>AES>AOS.

Adsorption of surfactants onto kaolin
Journal of Physics: Condensed Matter, 1989In support of an enhanced oil-recovery programme, surfactant adsorption by kaolin and silica from aqueous solution has been studied as a function of several parameters. The resulting isotherms show four distinct steps which are interpreted in terms of different modes of adsorption.

Surfactant adsorption from aqueous solutions
Pigment & Resin Technology, 1972Dispersant and surfactant additives, although used in minor amounts, exert a major influence in latex paints, controlling, for example, long‐term and freeze‐thaw stability in the can, application properties, and the opacity, gloss, and scrub resistance of the dry film.
