摘要： 用新合成的3-(二乙醇)氨丙基硅氧烷(DEAP)、3-(氮杂18-冠-6)丙基硅氧烷(BCP)作固定相,对二取代苯异构物进行液相色谱分离,研究流动相组成,pH值及其K+离子浓度对色谱行为的影响。探讨溶质保留机理,并比较DEAP、BCP与ODS的色谱性能。

关键词: 键合固定相, 二取代苯异构物, 色谱分离

Abstract: The chromatographic performance of two bonded stationary phases:3-(ethylene-glycol)-amino propylsilicon(DEAP) and 3-(aza-18-crown-6)propylsilicon(BCP),has been compared through the separation of some polar disubstituted benzene isomerides.The influence of organic solvent content,pH and potassium ion concentration in mobile phase on solute retention behavior has been investigated.The retention mechanism of the solute on various chromatographic systems has been discussed.

Key words: bonded stationary phase, disubstituted benzene isomeride, chromatography separation
