Abstract
Herein, we have investigated the mixed micellar behavior of carboxylate anionic dimeric surfactants (CAD12 and CAD16) with commercial surfactants; anionic type i.e., sodium dodecyl sulfate, cationic i.e., cetyltrimethylammonium bromide and nonionic i.e., polyethylene glycol p-(1,1,3,3-tetramethylbutyl)-phenyl ether. The CMC values of mixed surfactants obtained from conductivity data decrease with a mole fraction of dimeric surfactants. The micellar characteristics (ideal CMC) and mutual interaction parameters (β) have been computed with the aid of theoretical models proposed by Clint, and Rubingh. In addition to this, thermodynamic parameters of micellization like 0 ΔG0mic, ΔH0mic, and ΔS0mic were evaluated and discussed.
