  Abstract

UV-Vis 분광도법을 이용하여 순수 물에서 TTAB(tetradecyltrimethylammonium bromide) 계면활성제분자의 미셀화와 그 용액에서 4-할로겐화 페놀유도체들의 가용화에 대해 연구하였다. 또한 이들 물성에 미치는 NaCl과 n-부탄올의 효과를 조사 함으로써 미셀과 페놀유도체와의 상호작용과 미셀 내에서 가용화되는 위치를 추정하였다. 그 결과, 미셀화에 대한 값과 가용화에 대한 값은 모두 음의 값을 나타내었으며, 첨가제의 종류와 농도에 따라 이들 열역학적 함수값들은 각기 다른 변화를 보였다. 즉, NaCl의 농도를 증가하였을 때 와 값은 모두 감소하였다. 그러나 n-부탄올의 농도를 증가할수록 값은 감소한 반면에 값은 오히려 증가하였다. 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.
