چکیده

The current communication is focused on preparation and effect of various counter-ions on micelle behavior of N-methylhexadecylamine and ethylene diaminetetraacetic acid dianhydride-based carboxylate anionic gemini surfactant (G16). Structure elucidation of G16 has confirmed by FT-IR, ¹H-NMR and ¹³C-NMR. Further, the various surface studies of G16 in aqueous solution as well as in the presence of different counter-ions have been evaluated. The aqueous solution of G16 showed CMC i.e. 1.8 × 10⁻² mmol/L whereas, tremendous reduction in CMC of G16 has been observed i.e. 6 × 10⁻³ mmol/L in the presence of 10⁻¹ M sodium salicylate. In addition, the Krafft temperature of G16 was found to be <0 °C, revealing higher solubility aspect of compound.
