The influence of surface-active agents on kaolinite
article
The influence of surfactants (CTAB and SDS) on suspensions of monoionic kaolinite (Na<sup>+</sup> and H<sup>+</sup> form) was investigated by adsorption, sedimentation, turbidity, electroosmosis, and rheological measurements, at pH = 3.3 and 10.0. Only small differences are found between the Na<sup>+</sup> and H<sup>+</sup> forms of the kailinite. The data can be accounted for satisfactorily by a mathematical model based on the DLVO theory for face-face, edge-edge, and edge-face interactions, if some assumptions on the local ψ<sub>δ</sub> potentials near edge and face type surfaces are introduced. © 1981 Academic Press, Inc.
