摘要： 在溶液体系中通过自由基引发长链碳烯-1、二乙烯苯和乙烯基二氧化锆交联聚合反应得到聚长链碳烯-苯乙烯包覆二氧化锆固定相.考察了这种交联聚合物包覆柱填料的色谱性能和化学稳定性,并用这种填料分离了稠环芳烃和碱性化合物.

关键词: 二氧化锆, 交联聚合物包覆固定相, 液相色谱柱填料

Abstract: Novel alkyl and aromatic polymer-encapsulated zirconia-based packings for HPLC stationary phase were synthesized by radical polymerization of olefinic hydrocarbon and divinylbenzene with vinyl-modified zirconia in solution. SEM and 13C CP/MAS NMR were used to determine the physical properties of these stationary phases. Chromatographic characteristics were evaluated, and pH stability was also examined. Its superior performance for the separation of mixtures of polycyclic aromatic hydrocarbon and anilines were demonstrated.

Key words: Zirconia, Cross-linking polymer-encapsulated packing stationary phase, Liquid chromatographic column filler
