Résumé : |
The micellization behavior of three cationic gemini surfactants, C16H33N+(CH3)2(CH2)SN+(CH3)2C16H33, 2Br– (s = 4, 6, 10) have been studied in the presence of 1% (w/v) and 5% (w/v) polyethylene glycol-600 (PEG-600) by conductivity measurements at 300–320 K. From the conductivity data the critical micelle concentration, the degree of counterion ionization (α) and the thermodynamics of micellization ΔGo m, ΔHo m, ΔSo m, of the gemini surfactants have been determined. The micellar parameters show a significant dependence on the spacer length and as well as amount of polymer. |
