摘要: 本文研究了具有特殊结构的氢硼酸金属有机络合物的反相色谱及机理。在Micropak C18柱上,加入含离子试剂的甲醇-水作为流动相,通过用电导法测定流动相电性能,Break-through法测定离子试剂在固定相上的吸附量及制备色谱法研究各流分组成,认为此类化合物的保留机理为动态离子交换过程。

Abstract: Retention mechanism of reverse phase liquid chromatography of hydroborate organometallic complexes with novel structures was investigated. Separation was achieved on a Micropak C18reversephase column with a mobile phase of methanol-water system in which optimized ionic alkyl compounds were added as an ion reagent. The electric properties of the mobile phase, the role of absorption of the ion regents on the stationary phase, and the eluted constituents have been determined by conductance, Break-Through method and prepar ation chromatography, respectively. The influence of the concentration and type of the added ion reagents, and the composition of varying mobile phase on k'values were also discussed. It is concluded that the dynamic ion-exchange process is considered as the controlled mechanism.
