The interaction of the dye Eosine Y (I) and the nonionic surfactant Triton X 100 was studied by spectrometry. The equilibrium constant K and the no. of surfactant mols. bound to the dye mol. N were obtained. The presence of Na2SO4 as additive enhanced the dye-surfactant interaction, whereas the presence of urea weakened the interaction. Ionic surfactant having the same charge as that of I decreased the interaction between them due to electrostatic repulsion, while ionic surfactant having opposite charge to I increased the interaction.
