Abstract :The interaction between methyl red insert ignore into journalissuearticles values(azo dye); and cetylpyridinium chloride insert ignore into journalissuearticles values(cationic surfactant); in the methanol-water system were studied using a spectrophotometric technique. Variable parameters like constant dye concentration and its structure, surfactant concentration, pH, absorbance, and solvent composition were studied. Using the UV-Vis technique, critical micelle concentrations insert ignore into journalissuearticles values(CMCs); of cetylpyridinium chloride were measured with methyl red. The spectral data were analyzed and determined the differential absorbance, binding and partition constants, partition coefficient, the Gibbs free energy of binding and partition in mixed solvent media insert ignore into journalissuearticles values(0.1, 0.2, 0.3, 0.4 volume fraction insert ignore into journalissuearticles values(v.f.);s of methanol, respectively);.
