Adsorption of cationic and nonionic surfactants on a SiO2 surface from aqueous solutions: 2. Adsorption of dodecylpyridinium bromide and Triton X-100 from mixed solutions was written by Kharitonova, T. V.;Ivanova, N. I.;Summ, B. D.. And the article was included in Colloid Journal in 2005.Product Details of 104-73-4 This article mentions the following:
Adsorption of cationic (dodecylpyridinium bromide) and nonionic (Triton X-100) surfactants from their mixed aqueous solutions on a SiO2 surface at pH 3.6, 6.5, and 10 was studied by the UV spectroscopy, capillary zone electrophoresis, and wetting measurements. The adsorption of cationic and nonionic surfactants from mixed solutions is accompanied by synergistic effects manifesting themselves as an enhanced adsorption of both surfactants compared to their adsorption from individual solutions The effect of 2nd component becomes most pronounced under conditions when differences in adsorption abilities of individual surfactants are rather large (at pH 3.6 and 10). The adsorption of surfactants from mixed solutions can be controlled by the adsorption ability of components via the variations in solution pH. In the experiment, the researchers used many compounds, for example, 1-Dodecylpyridin-1-ium bromide (cas: 104-73-4Product Details of 104-73-4).
1-Dodecylpyridin-1-ium bromide (cas: 104-73-4) belongs to pyridine derivatives. Pyridine has a conjugated system of six π electrons that are delocalized over the ring. The molecule is planar and, thus, follows the Hückel criteria for aromatic systems. Pyridine derivatives are also useful as small-molecule α-helix mimetics that inhibit protein-protein interactions, as well as functionally selective GABA ligands.Product Details of 104-73-4
