Preparation and Characterization of Bonded Stationary Phase Containing Monoaza Crown Ether for High-Performance Liquid Chromatography
摘要:
Silica gel bonded stationary phases containing monoaza crown ether was synthesized via a series of solid-liquid phase reactions.The bonded molecular structure was characterized by chemical and instrumental analyses.The bonded stationary phase was provided with complexing ability with copper ion as well as hydrophobic property.The chromatographic retention behaviours of some substituted polar phenol derivatives,organic acids and bases on the bonded stationary phase were studied using methanol and/or aqueous solution of dibasic potassium phosphate buffer as mobile phase.When copper ion was added to the mobile phase at pH 5.4.the retention of substituted phenols became strong.
