ABSTRACT
Polarized visible attenuated total reflection spectrometry with a glass slab optical waveguide revealed that when a hydrophobic dye, curcumin, was adsorbed onto the cetyltrimethylammonium chloride (CTAC) reverse micelles immobilized on a glass surface, in an undissociated form, the curcumin was perpendicular to the surface plane, while in a dissociated form, the curcumin was parallel to the plane. This implies that the former may be located in the CTAC monolayer while the latter may be located in the reverse micellar water phase immobilized on the plane.
