摘    要:采用分光光度法测定了苯酚在非离子表面活性剂单相胶束溶液中和在非离子表面活性剂两相浊点萃取时凝聚层相中的增溶结果.实验表明:溶质在凝聚层相的增溶与表面活性剂形成胶束的结构有关.当凝聚层相的表面活性剂形成正相胶束时,溶质在凝聚层相的增溶规律和在表面活性剂胶束溶液中的增溶规律一致;当凝聚层相的表面活性剂形成反相胶束时,溶质在凝聚层相和在溶液相的浓度关系可理解为在这两种溶剂之间的分配随着凝聚层相的含水率逐渐降低趋近于一定值,溶质的分配系数也趋近于一定值.

关 键 词:苯酚  增溶  非离子表面活性剂  浊点萃取  凝聚层相

Abstract:Solubilization of phenol in micellar solution of nonionic surfactant and in coacervate phase of cloud point extraction were investigated with spectrometer method The result showed that solubilization of phenol in coacervate phase was related to the structure of surfactant micelle If the surfactant in coacervate phase forms a normal micelle, solubilization of phenol in coacervate phase is the same as that in surfactant solution If the surfactant in coacervate phase forms a reverse micelle, the concentration relationship of phenol in coacervate phase and in aqueous phase can be regarded as the solute partition in these two kinds of solvent When the water content in coacervate phase decreases to a constant value, the partition coefficient of phenol approaches a constant
Keywords:phenol   solubilization   nonionic surfactant   cloud point extraction   coacervate phase
