We report on the structure of adsorbed layers of sodium dodecyl sulfate (SDS) and tetradecyltrimethylammonium bromide (TTAB) on titanium dioxide (rutile) and kaolinite, and of TTAB and hexadecyltrimethylammonium bromide (CTAB) on quartz imaged by atomic force microscopy above their respective critical micelle concentrations (in the plateau adsorption region). The surfactants all form globular surface micelles on these three substrates, but under very different conditions. Adsorbed micelles of SDS are found at pH's less than the point of zero charge of rutile, whereas TTAB and CTAB adsorbed micelles are found only above the points of zero charge of rutile and quartz, respectively. Adsorbed SDS micelles are observed on the terraced edges of kaolinite particles, which are positively charged under acidic conditions. In contrast, adsorbed TTAB micelles are observed only on the anionic kaolinite basal plane.

“…Evidence for the incorporation of counterions (Br or C1-) into the bilayer comes from the calorimetric study of Wierer and Dobias (1988). Kunyima et al (1990) provide some evidence that, at very low surfactant concentrations, local monolayers (hemimicelles) and local bilayers (admicelles) may form at clay mineral surfaces.…”

Abstract--Adsorption of cetylpyridinium chloride (CPC) onto kaolinite can be followed using the electroacoustic effect. The dynamic mobility, measured at a frequency of l MHz, varies from about -2 to +I x 10 s m E V-i s-J in a number of steps, reflecting the adsorption of two separate layers, with the bilayer being more obvious, especially at pH 5-8. The behaviour at different pHs reflects the different charge characteristics of the basal cleavage planes and the crystal edges. When the amount of added CPC is equal to the cation exchange capacity of the clay, the kinetic charge changes from negative to positive and there is a pronounced break in the conductivity curve. It is also possible to estimate the edge to face area from such measurements and so obtain a measure of the aspect ratio of the clay crystallites. The (minimum) value for this clay is about 5: I.
