چکیده
|
This study delves into the investigation of the physicochemical characteristics and solubilization patterns of ar-27 dye within micellar environments containing the cationic surfactant ctabr, in conjunction with various electrolytes. the primary aim is to explore the augmented sequestration of ar-27 dye and its interplay with ctabr micelles through the utilization of uv-visible spectroscopy. the outcomes reveal a substantial enhancement in dye entrapment when electrolytes are introduced into ctabr micellar solutions compared to ctabr alone. specifically, the partition coefficient (𝐾𝑥) for ar-27 dye in ctabr media devoid of salt stands at 5.29 x 10^5, whereas in combination with nacl, kcl, and nh4cl, the 𝐾𝑥 values escalate to 1.46 x 10^6, 1.84 x 10^6, and 2.57 x 10^6, respectively. furthermore, the binding constants (𝐾𝒃) for ctabr, ctabr/nh4cl, ctabr/kcl, and ctabr/nacl are determined as 4.8 x 10^3, 4.4 x 10^4, 2.6 x 10^4, and 1.84 x 10^4 dm^3/mol, respectively. lower gibbs free energy values indicate a deeper penetration of dye molecules into the micelles. to sum up, this research underscores the pivotal role of incorporating electrolytes into ctabr micellar media in augmenting the sequestration of ar-27 dye. these findings offer valuable insights into the physicochemical attributes and solubilization dynamics of ar-27 dye within ctabr micellar environments, enhancing our comprehension of the interactions between the dye and micellar structures.
