“…And while, the interaction between headgroups is positive. In the presence of NaCl, the degree of crook for the curved hydrophilic chain on the C12AS molecule [11] decreases because of higher ionic strength in aqueous solution, and the fornicate oxyethylene group of OP-10 [1] trend to partly stretch due to the increase in the hydrophobic environment, all of which make the steric effect of headgroups reduce, consequently favoring the attractive interaction between the headgroups of two surfactants. Then, the contribution to the interaction between two surfactants may result mainly from the steric effect between the headgroups of surfactants in aqueous NaCl solution, which in turn makes b 12 more negative.…”

“…For binary mixtures, thermodynamic parameters of micellization, enthalpy change (DH M ), free energy change on non-ideal state (DG M ) and on ideal state (DG M ideal ), and the entropy change (DS M ), can be written respectively as the below equations [4,11,23].…”

“…A larger number of investigations [4][5][6][7][8][9][10][11][12] have been reported the interacting behaviors for the mixed surfactant systems in aqueous solutions in the absence of inorganic salts. Nevertheless, in many engineering applications, the inorganic salts always exist In aqueous solution containing the NaCl of 0.25 mol/L, the micellization of binary mixtures of sodium dodecyl diamino sulfonate (C12AS) and octylphenol polyoxyethylene ether (10) (OP-10) have been investigated employing both the UV-vis spectroscopy method, using pyrene as a probe, and the tensiometric method.…”

“…However, the micellar behaviors of zwitterionic-nonionic surfactants in aqueous solution containing inorganic salt have rarely been investigated. In this paper, the attempt was made to investigate the micellar behavior between an amino sulfonate amphoteric surfactant, n-dodecyl diamine sulfonate (C12AS) developed by our group [11,16], and nonionic surfactant octylphenol polyoxyethylene ether (10), OP-10, in aqueous solution, especially in the presence of sodium chloride. The main purpose of this investigation is to explore the micellar behavior of mixed surfactant systems as well as the composition of mixed micelles in aqueous solution containing sodium chloride of 0.25 mol/L.…”

A molecular‐thermodynamic approach was adopted to predict the value of mixed critical micelle concentration (cmc) for the binary surfactant mixtures constituted by an amino sulfonate amphoteric surfactant, sodium 3‐(N‐dodecyl ethylenediamino)‐2‐hydropropyl sulfonate (abbr. C12AS), and a nonionic surfactant, octylphenol polyethylene ether (OP‐n, where n denotes the average number of oxyethylene glycol ether). In this investigation, considering two positive charges on the hydrophilic group of C12AS, which is unlike to conventional zwitterionic surfactants having one positive charge (such as, alkylbetaine, etc.), three schemes were designed to obtain the geometric parameter describing the dipole structure of C12AS. According to the selected optimum scheme, four cases corresponding to the different conformations of both the headgroup and the hydrocarbon chain of surfactant were discussed. The results show that the predicted value of mixed cmc for the C12AS/OP‐n mixtures agrees well with the experiment value. The deviation of the predicted value from the experimental value can be explained by the effect of the hydrophilicity of OP‐n on the process of micellization. © 2017 American Institute of Chemical Engineers AIChE J, 2017

The micellization behavior of binary mixtures of sodium n-dodecyl diamine sulfonate (C12AS) and octylphenol polyoxyethylene ether (10), OP-10, in aqueous solutions at pH 3.5, 6.0, and 8.5 was investigated, and the values of mixed critical micelle concentration (C M ) were determined by both UV-vis spectroscopy using pyrene as a probe and by tensiometry. Within the framework of the pseudophase separation model, four thermodynamic models were adopted to describe the micellization parameters including the interaction parameters ( 12 ) between two surfactants, the components in real and ideal mixed micelles, the activity coefficients in mixed micelles, the thermodynamic parameters, and the thermodynamic stability. The experimental values of C M , inferior to the ideal values, show nonideal mixing; the negative values of 12 obtained from Rubingh's, Rodenas's, and Motomura's models mean the synergistic effect. Although there exist some divergences in the micellization parameters predicted by the three treatments, similar results were obtained, indicating the validity of these models in this investigation. Based on the calculation errors, Rubingh's model is best to describe the interacting behavior between the two surfactants in this investigation. Thermodynamic parameters predicted by the three treatments show a spontaneous process of micellization and an entropic contribution in the formation of mixed micelles. Different acidities of solutions result in different stabilities of micellization. The stability in feeble acidic solution is higher than in acidic or basic solution, and the stability in basic solution is slightly superior to that in acidic solution. All the above described phenomena can be explained rationally by the electrostatic effect of head groups of C12AS, the steric effect of head group for two surfactants, the molecular structures of surfactants, the influence of added counterion, and so on.
