| Popis: | Interactions among the oppositely charged polymer and surfactant are significantly complex in comparison to the interaction between an ionic surfactant and nonionic polymer vis-a-vis the physicochemical properties of the resulting polymer–surfactant solutions. In this work, we have deliberated upon the interactions taking place in between a water-soluble anionic polymer, sodium alginate (SA), with a cationic amphiphile, hexadecylbenzyldimethylammonium chloride (C16BzCl), in absence and in presence of sodiumchloride (NaCl) and sodium salicylate (NaSl) employing tensiometric, conductometric, and rheometric measurements. The system was characterized by evaluating physicochemical properties like viscosity curves, critical aggregation concentration (cac), and critical micelle concentration (cmc) as a function of C16BzCl concentration. The results show significant differences between the ions furnished by NaCl and NaS1 which could be justified on the basis of effect of solubilization, differential binding of NaSl to polymeric backbone, electrolyte effect, and the solvent modifying tendencies in contrast to the only salt effect of NaCl. |
