Abstract: A spectrophotometric method was used to study the interaction of an anionic dyeECAB with a nonionic surfactant Triton X-100. The binding constant of ECAB withthe TX-100 micelles and the number of binding sites were calculated by a modifiedSepulveda's method. The effect of an anionic surfactant SDS on the interaction betweenthe ECAB and the TX-100 was also investigated.

Key words: Nonionic surfactant, Dye, Spectrophotometry
