General isotherm equation for adsorption of surfactants at solid/liquid interfaces. Part 2. Applications

Surface Heterogeneity of Passively Oxidized Silicon Carbide Particles: Hydrophobic–Hydrophilic Partition

“…According to several previous papers concerning the adsorption of cationic surfactants on silica (44)(45)(46), the second step of the adsorption is attributed to hydrophobic interactions. Here, the hydrophobic interaction is due to the surfactant ions already bound to the surface by the polar head group, the alkyl chains pointing out in the bulk solution or directly to the interaction between the surfactant and the uncharged surface.…”

Adsorption and Desorption of Triton X-100 in Polystyrene Particles with Different Functionality

“…sorption of surfactants (4)(5)(6)(7)(8)(9)(10). Many of them tend to the simple Langmuir isotherm (11,12) under certain conditions.…”

Thermodynamic Approach to the Wetting of Solids by Surface-Active Agents: A Supplementary Approach to the Gibbs Formalism

“…This borderline relation permits us to suitably describe the experimental data shown in the literature (4,5,(17)(18)(19)(20)22). This can be illustrated by a very complete study recently published by Koopal et al (24) about the effects of cationic surfactants on wettability, colloidal stability, and the flotation of silica.…”

“…For example, adoption of Eq. [5] implies that the variation of the interfacial tension with the chemical potential of 2, at constant surface entropy, surface number of moles of solvent, and area, can be written as…”
