Description
Summary:Micellar properties of the binary and ternary surfactant combinations of sodium dodecyl benzene sulfonate, polyoxyethylene sorbitan monolaurate, and polyoxyethylene lauryl ether have been investigated in detail by employing tensiometric, fluorometric, and conductometric techniques in aqueous medium. The critical micelle concentrations, counterion binding, interfacial adsorption, energetics of micellization as well as adsorption, micropolarity, aggregation number, composition of the micellar species, and molecular interaction parameters in the mixed micelles have been evaluated. The physicochemical properties of the systems are observed to depend on the solution composition. We have estimated the characteristics of the micellar aggregates such as composition, activity coefficients, critical micelle concentration, and synergism of the binary and ternary surfactant systems following the treatments of Clint, Rubingh, Motomura, et al. and Rubingh and Holland.
