摘要：

通过在聚合诱导胶体凝聚法制备的二氧化锆微球表面上沉积、交联长链碳稀和聚丁二烯,制备了复合型二氧化皓固定相.探索了影响反应的主要因素,并对其色谱性能进行了评价.用分离实例说明该固定相对中性,特别是碱性化合物具有优良分离性能,显示反相色谱特征.

Abstract:

Novel reversed-phase packings (C8-PBD-ZrO2, C18-PBD-ZrO2) were prepared by depositing and cross-linking 1-octene(C8) or 1-octadecene(C18) and polybutadiene(PBD) onto th surface of porous zirconia microspheres which were synthesized by PICA (polymerization-induced colloid aggregation) method. The reaction conditions for the synthesis of these stationary phases were studied. The neutral and basic compounds were separated on these column packings.

Key words: Zirconia, Long-alkenylene-PBD coating, LC stationary, HPLC
