“…Values of CMC determined from the θ-log C curves (Figs. 1-3) are close to those determined from the surface tension isotherms [28,29] and there is the negative deviation of the CMC values for CTAB+TX-100 and CTAB+TX-114 mixtures as a function of α in contrast to the TX-100 +TX-114 mixtures where this dependence is almost linear (Figs. S4-S6).…”

“…It appeared that the shape of γ SL −log C curves (Figs. S8-S10) for the PTFE-solution interface is nearly the same as for the γ LV −log C ones [29]. However, there are some differences between the maximal surface excess concentration at the water-air and PTFE-water interfaces for the given binary systems which can suggest that the adsorption at the water-air and PTFE-water interfaces is not the same in all cases.…”

“…The shape of the contact angle isotherms for nylon 6 (Figs. 7-9) both at the constant composition and concentration of the mixtures is the same as for PMMA and similar to that of the isotherm of surface tension [29], therefore it was possible to determine the values of CMC. The values of the CMC determined in this way are similar to those obtained from the isotherm of contact angle on PTFE and PMMA and the isotherm of surface tension (Figs.…”

“…In turn, these parameters directly depend on the adsorption of the surfactants at the solid-air, liquid-air and solid-liquid interfaces and indirectly on their behavior in the bulk phase. Because the shape of the contact angle isotherms for the studied systems is similar to that of surface tension [29], it should be expected that from these isotherms it is possible to determine the critical micelle concentration (CMC) of the studied mixtures. Values of CMC determined from the θ-log C curves (Figs.…”

This work is a discussion on the applicability of the Gibbs-Duhem relationship. We show that it does not exist in the nonextensive thermodynamic approaches. To illustrate this, we have chosen to present the properties of three surfactants (dodecyltrimethylammonium bromide (DTABr), sodium dodecyl sulfate (SDS), sodium decanoate (NaDec) in aqueous solutions at 298 K) whose behavior after the micellization threshold can be described by the rules of the nonextensive thermodynamics. We show that the Gibbs-Duhem relationship does not apply to these systems and we propose to formalize the deviation from this law. The consequences of this study are discussed for the different approaches that involve the use of Gibbs-Duhem relation in the case of micellized solutions. In particular, the applicability of the Gibbs relation which links surface tension and the chemical potentials of solutes is considered. More generally, this study warns against the blind application of the Gibbs-Duhem (or Gibbs) relation, to any system.

Surfactant effect on cloud condensation nuclei for two‐component internally mixed aerosols

This work presents experimental data on the cloud condensation nuclei (CCN) activity of two‐component mixtures containing surfactants. Nine binary systems were tested combining strong ionic (sodium dodecyl sulfate) and nonionic surfactants (Zonyl FS‐300 and Triton X‐100) with nonsurfactant compounds (glucose, ammonium sulfate, or sodium chloride). Control tests were performed for systems combining organic (glucose) and inorganic compounds (ammonium sulfate or sodium chloride). Results show that CCN activity deviates strongly relative to predictions made from measurements of bulk surface tension. Köhler theory accounting for surface tension reduction and surface partitioning underpredicts the CCN activity of particles containing Zonyl FS‐300 and Triton X‐100. Partitioning theory better describes data for Zonyl FS‐300 and Triton X‐100 when limiting surface adsorption to 1.5 monolayers of the growing drop. Deviations from predictions were observed. Likely explanations include solute‐solute interactions and nonspherical particle shape. The findings presented here examine in detail the perturbation of CCN activity by surfactants and may offer insight into both the success and limitations of physical models describing CCN activity of surface active molecules.
