【 摘 要 】

The solubilization of p-bromophenol by the micellar system of TTAB(tetradecyltrimethylammonium bromide) and the micellization of TTAB were studied by the UV-vis spectrophotometric method simultaneously. And the effects of temperature on these properties have been measured for the thermodynamic study. The results show that the ¥ÄGs o and ¥ÄHs o values are negative and the ¥ÄSs o values are positive for the solubilization of p-bromophenol within the measured range. On the other hand, the ¥ÄGm o values are negative and the ¥ÄHm o and ¥ÄSm o values are positive for the micellization of TTAB. The effects of additives such as n-butanol and NaCl have been studied also for both properties and the relationship between these two properties has been also studied. From the results, we can postulate the solubilization site of p-bromophenol in the micelle.
