A reinterpretation of the hydration of micelles of dodecyltrimethylammonium bromide and chloride in aqueous solution.
The hydration of dodecyltrimethylammonium (DTAB) micelles is reinterpreted in light of the results of the companion paper (immediately preceding this paper) that showed that the location of the spin probe 16-doxylstearic acid methyl ester (16DSE) changes as a function of the aggregation number, N, of anionic micelles, i.e, that it does not conform to the zero-order model (ZOM). The ZOM requires...
متن کاملInteraction of cationic surfactants with carboxymethylcellulose in aqueous media.
We have examined the polymer-surfactant interaction in mixed solutions of the cationic surfactants, i.e., dodecyltrimethylammonium chloride, dodecyltrimethylammonium bromide, tetradecyltrimethylammonium bromide, hexadecyltrimethylammonium bromide, tetradecyltriphenylphosphonium bromide, and tetradecylpyridinium bromide and a semiflexible anionic polyelectrolyte carboxymethylcellulose in water a...
متن کاملInteraction of Tetradecyltrimethylammonium Bromide with Poly(acrylic acid) and Poly(methacrylic acid). Effect of Charge Density
The effect of polymer chalge density on the interaction of tetradecyltrimethylammonium brolnide <TrAB) with poly(acrylic acid) (PAA) and poly(methacrylic acid) (PMA) has been investigated usmc a surfactant-sensitive solid-state membrane electrode. The experimental results indi~te that the intenction with PAA begins at about the same equilibrium TTAB concentration wben the degree of ionization (...
متن کاملFormation of Worm-Like Micelles in Mixed N-Hexadecyl-N-Methylpyrrolidinium Bromide-Based Cationic Surfactant and Anionic Surfactant Systems
Through the descriptive and rheological characterization of worm-like micelles formed by N-hexadecyl-N-methylpyrrolidinium bromide and sodium laurate, the formation and properties of the worm-like micelles were affected by the concentrations of sodium laurate and temperature. Additionally, cryogenic transmission electron microscopy images further validated the formation of worm-like micelles.
متن کاملSedimentation in micellar solutions of tetradecyltrimethylammonium bromide
In the paper the results of experimental studies on the sedimentation process of barium carbonate (of mean particles diameter of 25 [μm]) in aqueous solutions of tetradecyltrimethylammonium bromide, have been presented. As the additives assisting in micellar association the sodium bromide and sodium salicylate, have been used. The sedimentation tests were carried out in the transparent cylinder...
