Employment of a useful liquid membrane electrode system to characterise the micelles of bile salts and other detergents in pure and mixed states

Interfacial and Micellization Behaviors of Binary and Ternary Mixtures of Amphiphiles (Tween-20, Brij-35, and Sodium Dodecyl Sulfate) in Aqueous Medium

“…The entropy of micellization has been obtained from the relation ⌬G m°ϭ ϪT⌬S m°n eglecting the enthalpy of micellization, ⌬H m°w hich could not be measured (13,23) in the Tronac-458 Isoperibol calorimeter (USA). The calorimeter can measure a minimum heat change of 1 cal.…”

“…The total area minimum values ( A min tot ) at CMC are obtained by the equations ͑ A min tot ͒ bin ϭ 10 18 /N͑⌫ max tot ͒ bin [13] and ͑ A min tot ͒ ter ϭ 10 18 /N͑⌫ max tot ͒ ter . [14] The CMC , ⌫ max tot , and A min tot values for the binary and ternary combinations are presented in Tables 2 and 3, respectively.…”

“…In recent years, with the above ends in view, detailed studies on mixed surfactant systems have been made (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13). The binary mixtures of nonionic-nonionic, nonionic-ionic, and ionic-ionic surfactants have been considered and experimental results have been analyzed and compared in the light of the proposed solution and thermodynamic theories of Clint (14), Motomura (15), Rubingh (16), and Sarmoria, Puvvada, and Blankschtein (17).…”

Thermodynamic and Interfacial Properties of DTABr/CTABr Mixed Surfactant Systems in Ethanolamine/Water Mixtures: A Conductometry Study

“…It is therefore worthwhile to consider the effect of an organic molecule that combines the properties of alcohol and amine as a single entity on the mixed micelle formation. A literature survey shows that considerable efforts have been made on the study of mixed surfactant systems [24][25][26] to characterize micelles and their formation in water.…”

Mixed micelles of alkylamines and cetyltrimethylammonium chloride

“…Although mixed micellar systems have been widely studied [10][11][12][13][14][15][16][17][18], mixtures of cationic surfactants have been less frequently examined and substantial deviations from their ideal behavior encountered [16,[19][20][21][22][23].…”
