Abstract :Simple and differential Uv/Visible spectroscopic method were used to monitored the interaction of Sodium dodecyl sulphate insert ignore into journalissuearticles values(SDS); and Sodium – N - laouryl sarcosinate insert ignore into journalissuearticles values(SLS); with crystal violet insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values( ); values and binding constant insert ignore into journalissuearticles values( ); values from which the free energy of partition insert ignore into journalissuearticles values( ); and the free energy of binding insert ignore into journalissuearticles values( ); were estimated. From the partition coefficient insert ignore into journalissuearticles values( ); values, it could be inferred that the solubilization of CV is more pronounced and spontaneous in the SDS than in the SLS micellar media.
