BEHAVIOR OF ANTHRAQUINOID ACID DYES IN AQUEOUS SOLUTION OF SODIUM DODECYL SULFATE

The behavior of an anthraquinoid acid dye in an aqueous solution of an anionic surfactant,sodium dodecyl sulfate,was investigated by electronic spectroscopy and gel permeation chromatography. The experimental findings suggest that above the cmc, one dye molecule is associated with one surfactant micelle.
