Adsorption Behavior of Curcumin onto Cetyltrimethylammonium Chloride Reverse Micelles Immobilized on a Glass Surface As Studied by Polarized Visible Attenuated Total Reflection Spectrometry with a Glass Slab Optical Waveguide

Abstract

Reagents and chemicals Curcumin (1,7-bis(4-hydroxy-3-methoxyphenyl)-1,6-heptadiene-3,5-dione), and cetyltrimethylammonium chloride (hexadecyltrimethylammonium chloride, CTAC) were obtained from Wako Pure Chemical. Cyclohexane, 1-hexanol and other chemicals
