dc.description.abstractIn this paper, the gemini surfactants of type alkanediyl-a-co-bis (alkyldimethylammonium) dibromide with different spacers containing s carbon atoms, referred to as 16-s-16 [C16H33(CH2)(2)N+(CH2)sN(+)(CH2)(2)C16H33.2Br-], (s=2, 6, 10 and Ar (8)) have been synthesized, purified and characterized in our laboratory. The interactions between geminis and their conventional monomeric surfactant hexadecyltrimethylammonium bromide (CTAB) have been studied using the conductivity and steady-state fluorescence quenching techniques at a certain micellar concentration range and certain temperature. Using the conductance data, the values of critical micelle concentrations (CMC) of the binary gemini-conventional mixtures having different compositions have been obtained. The micellar interaction parameters, (beta), were determined from the critical micelle concentration values using the approach of Rubingh's regular solution theory. Mixed systems were exhibited negative synergism due to positive beta values. The beta values were found as close to zero. This indicates that the mixed micelle formation is ideal for all studied mixtures. The micelle aggregation numbers (N-agg evaluated using steady-state fluorescence quenching at a total concentration of 2 mM for CTAB/16-s-16 (s= 2, 6, 10 and Ar (8)) systems. It was observed that contribution of conventional surfactants was always more than that of the geminis. Using the ratio of peak intensities, the micro-polarity, dielectric constant and binding constant (K-sv) of mixed systems were determined. (C) 2014 Elsevier B.V. All rights reserved.en_US
