Association of cationic surfactants to humic acid: Effect on the surface activity
(Elsevier, 2006)
Surface properties of aqueous solutions of mixtures of humic acid, HA, and a series of cationic surfactants, CnTAB, have been studied. For a fixed amount of HA, the concentration of surfactant at which micelle-like aggregates ...
The Interaction Between N-Isopropylacrylamide-Acrylic Acid-Ethyl Methacrylate Thermosensitive Polymers and Cationic Surfactants
(Taylor & Francis Inc, 2009-01-01)
The interaction between cationic surfactants and isopropylacrylamide-acrylic acid-ethyl methacrylate (IPA:AA:EMA) terpolymers has been investigated using steady-state fluorescence and spectrophotometric measurements to ...

Use of cationic surfactant-xylenol orange indicator in metals complexometry by back-titration with EDTA.
(Editora Unesp, 1996-01-01)
The interaction of the xilenol orange and commercial disinfectant containing itself cationic-surfactant allowed the use indicator up to pH 11 by back-titration with EDTA, and the determination of total or partial concentration ...

The effect of chain length on the melting temperature and size of dialkyldimethylammonium bromide vesicles
(Elsevier B.V., 2006-07-01)
Differential scanning calorimetry (DSc) and dynamic light scattering (DLS) were used to obtain the gel to liquid-crystalline phase transition temperature (T-m) and the apparent hydrodynamic radius (R-h) of spontaneously ...
Mixed Cationic Surfactant Vesicles in (Dioctadecyldimethylammonium Bromide)/NaCl and (Dioctadecyldimethylammonium Chloride)/NaBr Aqueous Dispersions
(Wiley-Blackwell, 2019-07-26)
One of the most challenging characteristics not fully understood yet of the cationic surfactant salt dioctadecyldimethylammonium (DODA(+)) halide is concerned with the effects of the counterion (usually Br- and Cl-) on the ...
Interaction Parameters of Surfactant Mixtures by Inverse Gas Chromatography
(IntechOpen, 2012)
The Inverse Gas Chromatography (IGC) has been used in the measurement of surfactant-surfactant interaction parameters at different percentages and temperatures in cationic surfactant mixtures. Specific retention volume ...
