摘　　要：采用油乳法制备了钛锆复合氧化物并系统评价了该填料的正相色谱性能。研究结果表明 ,该填料对碱性化合物有良好的分离选择性 ,峰形对称 ;但对酚类化合物强烈保留 ,峰形较差 ;中性化合物和碱性化合物的色谱行为均符合Titania zirconia microparticles were prepared by oil emulsion method and their normal chromatographic performance was evaluated by using ethanol cyclohexane, dichloromethane cyclohexane and chloroform cyclohexane as mobile phase. Basic compounds were separated well with symmetrical peaks, but acidic compounds such as phenol gives poorly peaks or remain a long time on the packing. The behavior of the neutral solutes and basic compounds is in accordance with the theory of adsorption chromatography proposed by Snyder.
