摘要

研究了十二烷基硫酸钠(sodium dedocyl sulfate, SDS)胶束体系对硝基苯的增溶作用, 考察了SDS浓度和SDS溶液中的NaCl质量浓度对硝基苯增溶作用的影响, 采用核磁共振(nuclear magnetic resonance, NMR)技术确定了硝基苯在SDS胶束中的增溶位置. 实验结果表明, 硝基苯的增溶量既随SDS浓度的增加而增加, 也随SDS溶液中NaCl质量浓度的增加而增加. 硝基苯在SDS胶束中的增溶位置靠近SDS的疏水内核.

Abstract

Solubilization of nitrobenzene in the sodium dedocyl sulfate (SDS) micelles was investigated. It was found that the amount of nitrobenzene solubilized in SDS micelles increased with increasing concentration of both SDS and NaCl. The solubilization site of nitrobenzene in the SDS micelles was determined by nuclear magnetic resonance (NMR) near the hydrophobic core of the SDS micelles.
