Abstract

The synergistic effect on surface tension reduction and micelle formation was systematically studied for the binary mixtures of sodium dodecyl sulfate (SDDS) and dodecyl trimethyl ammonium chloride (DDTMAC). Significant synergism of this system results in large negative values of parameters βo and βm, that measure the extent of the interaction between the two surfactants for mixed monolayer formation at aqueous solution/air interface and mixed micelle formation, respectively. The stoichiometry and equilibrium constant of the ion - pair complex formation between oppositely charged organic ions were also determined by means of the conductimetric method. Synergism affects through the formation of the equimolecular complex can then be verified.
