Gemini surfactant of the type N,N'-didecyl-N,N,N',N'-tetramethyl-N,N'-ethanediyl-diammonium dibromide referred as (10-2-10) was synthesized in our laboratory. It was observed that a decrease in the measured specific conductance of dye-gemini surfactant mixtures was caused by the formation of nonconducting or less conducting dye-surfactant associates. The aggregation of surfactant and dye takes place at a surfactant concentration far below the critical micelle concentration of the individual surfactant. The long-range electrostatic forces and short-range hydrophobic interactions are very important factors at the dye-surfactant aggregation in aqueous solutions. From conductivity data for dyes-gemini surfactant interaction such as micellar ionization degree, counterion binding, equilibrium constant and thermodynamic parameters of interaction were calculated. Thermodynamic parameters of interaction indicate that interaction of dye-(10-2-10) is enthalpy driven.eninfo:eu-repo/semantics/closedAccessCationic Gemini SurfactantReactive DyeIonization DegreeAssociation ConstantThermodynamic ParametersNonionic SurfactantsAbsorption-SpectroscopyMicelle FormationChain-LengthDyeAggregationMixturesBromidesConference Object241257495752Q4WOS:000310771200090
