Influence of Ca<sup>2+</sup> on the adsorption of different surfactants in the bentonite-water interface
Adsorption of surfactants of different nature on the bentonites/water interface and an influence of Ca2+ ions on the adsorption characteristics were investigated. The data obtained from adsorption isotherms were compared with RFA data. It was shown that cationic ABDMAC have a maximal adsorption and...

| description | Adsorption of surfactants of different nature on the bentonites/water interface and an influence of Ca2+ ions on the adsorption characteristics were investigated. The data obtained from adsorption isotherms were compared with RFA data. It was shown that cationic ABDMAC have a maximal adsorption and vertical orientation to the basal space of montmorillonite. In the case of nonionic oxyethylated alkylphenols molecules intercalate in to the interlayer and form bylaeyer structure parallel to the surface even at high concentrations. Anionic surfactant did not penetrate into interlayer and situated only on the external surface of bentonites. In the presence of calcium ions adsorption increase witch lead to more compact vertical orientation of molecules. |
