Simple and
differential Uv/Visible spectroscopic method were used to monitored the
interaction of Sodium dodecyl sulphate (SDS) and Sodium – N- laouryl sarcosinate (SLS) with crystal violet (CV) in pre-micellar
and post-micellar concentration range. The results showed that the peak of CV
at 590nm was unperturbed in CV/SDS system, but the intensity increased as surfactant
concentration increased, unlike in the CV/SLS system. This is an indication
that strong interaction occurred between CV and surfactants molecule.
Absorption data were also used to obtain partition coefficient () values and binding constant () values from which the free energy
of partition () and the free energy of binding () were estimated. From the partition coefficient () values, it could be inferred that the solubilization
of CV is more pronounced and spontaneous in the SDS than in the SLS micellar
media.
