Micellar properties of long-chain alkyldimethylbenzylammonium chlorides in aqueous solutions

Thermodynamics of Micellization of Alkyldimethylbenzylammonium Chlorides in Aqueous Solutions

“…The above results recalculated into the classical Stauff-Klevens (13,14) relation form the following expression, log cmc (25 • C) = 1.689 ± 0.023 − (0.3128 ± 0.0018)n, [8] with a correlation coefficient of 0.99997. Equation [6] is in a good agreement with the Stauff-Klevens relation obtained in our previous study (15) directly from conductivity measurements at 25…”

Self‐Probing of Micellization within Phenyl‐Containing Surfactant Solutions

“…The electronic absorbance spectra of aqueous solutions of BDHACl and SDBS, respectively, were collected (Supporting Information, Figures S1, S2 [23][24][25][26] ), a shoulder grows with [BDHACl] in the vicinity of ca. 325 nm.…”

“…Further, a plot of area under the differenced normalized band versus surfactant concentration (inset Figure 1 B) shows a clear break at the CMC value (0.48 mm) which is comparable to the reported value. [23][24][25][26] Thus, it is evident that steady-state fluorescence emission data can be used to probe the micellization process within aqueous BDHACl and is also useful in the determination of CMC value of the surfactant in a non-invasive fashion.…”

“…A CMC value of 0.10 mm was recovered, which is again in accordance with the literature value (data not shown). [23][24][25][26] Thus, this simple, non-invasive method based on steady-state fluorescence emission can potentially be employed for the measurement of CMC of BDHACl even in the presence of external additives.…”

“…in the maximum absorbance and red-edge realms), emissions were recorded for the surfactant concentration from 1. [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40] These values are obtained using different measuring techniques such as pendant-drop tensiometry, spectrophotometry, surface tension, and conductivity methods, among others. The reported CMC values of this surfactant vary from 1.2 mm to as high as 8 mm.…”
