| 摘 要： | 三种Pluronic嵌段共聚物（F108，P94和L64）胶束水溶液对萘、蒽、芘的增溶研究表明，它们在胶束和水相间的分配系数Kv值大小的顺序为：P94＞F108＞L64，这是由于具有较长PPO嵌段的Pluronic共聚物分子形成了较大内核的胶束，这种胶束有利于稠环芳烃的增溶。当指定Pluronic胶束体系时，Kv值随着稠环芳烃分子憎水性的增强（即分子苯环数目增加）而增大。这些规律同样反映在吸附等温线中。

| Abstract: | Solubilization of the polycyclic aromatic hydrocarbons in the aqueous micellar solutions of poly (ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide ) triblock copolymers have been investigated by UV-spectra measurements. Since Pluronic molecules with a long PPO block, for example P94 or F108, formed micelle with large core in volume, this resulted in a corresponding change of the partition coefficients ( Kv) of the polycyclic aromatic hydrocarbons between the micelle and water in an order: P94 > F108 > L64. When fixing the concentration of micelle, the value of Kv was enhanced in an order of naphthalene, anthracene and pyrene. |
