介绍了胶束电动色谱(MEKC)中六种阴离子表面活性剂的选择性差异,并研究了表面活性剂头部基团的结构影响。已确定表面活性剂结构可对保留率和选择性具有显著影响。线性溶剂化能关系(LSER)被用来研究溶质的大小,极性/极化率,和氢键特性在确定保留和选择性的作用。虽然溶质的大小和氢键接受能力被认为是溶质保留的最重要的因素,溶质的氢键特性对表面活性剂之间的选择性差异的影响最大。
The selectivity differences between six anionic surfactans in micellar electrokinetic chromatography (MEKC) are presented and the structural influence of the surfactant head‐group is investigated. It was determined that the surfactant structure can have a significant impact on retention and selectivity. Linear solvation energy relationships (LSERs) are used to study the role of solute size, polarity/polarizability, and hydrogen bonding characteristics in determining retention and selectivity. While both the solute size and hydrogen bond accepting ability were found to be the most important factors in solute retention, the hydrogen bonding characteristic of the solutes have the largest influence on selectivity differences between surfactants.
