同一非离子表面活性剂胶束对不同离子缔合物的作用,主要取决于离子缔合物及其中两个对离子的憎水性强弱,由此引起在胶束中增溶位置的不同。只有对组成离子缔合物的两个对离子憎水性很强且基本相似的体系,才可用非离子表面活性剂为增溶荆;有时还同时发生增敏作用。聚乙烯醇、明胶、阿拉伯胶等大分子物质,由于氢键作用及空间稳定作用,可作为大多数离子缔合物休系的分散剂,但增敏作用不强。
The effect of the same nonionic surfactant micelles on different ion-association compounds depends mainly on the hydrophobicity of the ion-association complexes and two of the ions, thereby causing differences in the solubilization sites in the micelles. Non-ionic surfactants can be used as solubilizing agents only for systems that are highly hydrophobic and substantially similar to the two counterions that make up the ion-associating species; sensitization is sometimes simultaneous. Polyvinyl alcohol, gelatin, gum arabic and other macromolecular substances, due to hydrogen bonding and steric stabilization, can be used as the dispersant for most ion-association rests, but the sensitization effect is not strong.
