【摘要】 无机电解质 K Cl使萘分子和 Pluronic嵌段共聚物 F10 8或 P94空胶束的第一步缔合平衡常数K1值和萘在胶束和水相间的分配系数 KV 值增大 ,即促进了萘的增溶 ,这是由于 KCl使胶束的聚集数增大 ,内核趋向主要由 PO构成所致。KSCN的作用则相反 ,它使胶束的聚集数减小 ,同时降低了内核的 PO含量 ,因而使萘在 F10 8和 P94胶束中的 K1和 KV 值降低更多还原

【Abstract】 Effects of inorganic electrolytes on solubilization for naphthalene in the micelles of Pluonic F108 and P94 aqueous solutions have been investigated by UV-method. Solubilizing capability of the Pluronic micelle for naphthalene was enhanced with addition of KCl since the micellar core became more hydrophobic and larger in size compared with the salt-free system. The effect of KSCN on the Pluronic micelles and solubilization for naphthalene was opposite to KCl.更多还原
