Abstract In the present study, the enantiomeric forms of hydrophobic amino acids ( l -tryptophan, l -tyrosine, and l -phenylalanine) were separated by molecularly imprinted capillary columns (MICC) via Capillary Electrochromatography (CEC) for the first time. The monomer ratio, crosslinker ratio, template molecule ratio, the porogen ratio and type, polymerization time, and also the effect of temperature were examined to increase the permeability properties of MICC. FTIR, SEM and BET analyses were realized for the characterization of MICC. The effect of the electric field, organic solvent ratio, and pressure were carried out experimentally to determine the optimum conditions. The separation performances of MICC and the non-imprinted capillary columns (NICC) were compared electrochromatographically.

分子印迹毛细管柱电色谱分离疏水性氨基酸对映体

摘要 本研究首次通过毛细管电色谱（CEC）通过分子印迹毛细管柱（MICC）分离疏水性氨基酸（l-色氨酸、l-酪氨酸和l-苯丙氨酸）的对映体形式。检查单体比例、交联剂比例、模板分子比例、致孔剂比例和类型、聚合时间以及温度的影响，以增加 MICC 的渗透性能。实现了 FTIR、SEM 和 BET 分析来表征 MICC。对电场、有机溶剂比例和压力的影响进行了实验，以确定最佳条件。MICC 和非印迹毛细管柱 (NICC) 的分离性能通过电色谱进行了比较。
