Adsolubilization of naphthalene and alpha-naphthol in C(n)TAB admicelles
The adsolubilization of organic solutes with similar structures but varying polarities, both individually and in pairs, in C(n)TAB (n = 12, 14, 16) admicelles was studied. The partition coefficients were calculated for each system to determine the suggested locus of adsolubilization within the admicelles, through which we hope to gather a better understanding of the interior nature of the adsorbed aggregates. By measuring the adsolubilization of organic solutes with varying polarities, we will investigate the adsolubilization capacities of the core and palisade regions within the admicelle and their interactions within the admicelle. Decreasing the tail length will allow for the effects of surfactant tail length and admicelle packing on the adsolubilization process to be examined. The results indicate that there is not a clear relationship between surfactant tail length and the maximum solute adsolubilization, Through an examination of the plateau adsorption and the area per molecule for each surfactant, suggestions concerning the packing of the admicelles have been proposed to explain the observed trends. The calculated partition coefficients have been used to partially validate the proposed theory.
