【 摘 要 】

The micellization of TTAB(tetradecyltrimethylammonium bromide) and the solubilization of 4-halogenated phenol isomers in aqueous solution of that surfactant in water have been studied by the UV-Vis spectrophotometric method. Those properties in aqueous solutions of NaCl and n-butanol have been also measured to determine the interactions between the micelle and 4-halogenated phenols and the solubilized sites of those molecules in the micelle. The results show that the values of and are all negative and the trends of those values depend on both the kinds and the concentrations of additives. Namely, by adding NaCl both and values are all decreasing, but by adding n-butanol the value decreases and the value increases.
