Thermodynamics of ionic surfactant micelle—comments

Journal of Colloid and Interface Science, 1987
Abstract The assumptions made in deriving a recently published micellar Gibbs-Duhem equation applicable to micellar solutions of ionic surfactants which may contain several counterion species are stated explicitly and reviewed critically. Possible improvements are suggested.

Thermodynamics of Micelle Formation of Chlorhexidine Digluconate

The Journal of Physical Chemistry, 1995
The critical micelle concentrations (cmcs) of chlorhexidine digluconate (CG) in aqueous solution were determined over the temperature range 15-40 "C by a method based on deconvolution into Gaussians of the second derivative of the conductivity/concentration data. The mass-action model was modified in order to calculate the thermodynamic parameters (Ac",

Molecular Thermodynamics of Giant Micelles

2007
This chapter summarizes the geometrical relations for spherical, globular, and rodlike micelles, consistent with molecular packing considerations, and develop general thermodynamic equations that govern the formation of rodlike micelles. It shows how to estimate the molecular constants appearing in the free energy expressions, describes the ...

Molecular-Thermodynamic Theory of Micellization of pH-Sensitive Surfactants

Langmuir, 2006
A predictive, molecular-thermodynamic theory is developed to model the micellization of pH-sensitive surfactants. The theory combines a molecular-thermodynamic description of micellization in binary surfactant mixtures with the protonation equilibrium of the surfactant monomers.

Thermodynamics of hexadecyltrimethylammonium bromide micelle formation

Russian Journal of Physical Chemistry A, 2017
The thermodynamic parameters for CTAB micelle formation (ΔН, ΔG, ΔS) are calculated at different temperatures. Critical micelle concentrations CMC1 are determined. The possibility of determining CMC2 is demonstrated.

Thermodynamics of mixed micelles: Determination of the aggregate composition

Journal of Colloid and Interface Science, 2008
In most studies concerning surfactant mixtures, the determination of the composition of mixed micelles is often tricky. This composition can be obtained by different ways. One of them, undoubtedly the most used, supposes, a priori, that the surfactant in the micelle follows the regular solution model.
