Preparation of Modified Porous Polyionic Liquid Microspheres and Their Application in High Performance Liquid Chromatography

Polymer microspheres have been widely used as a stationary phase in liquid chromatography. We characterized the properties of the novel polyionic liquid microspheres prepared and explored their application as a stationary phase in liquid chromatography. Cytosine, uracil, benzene, benzene homologs and alkaloids were successfully separated by liquid chromatography with the polymer microspheres as packing materials in the chromatographic column.
