二茂铁衍生物在四氢呋喃－甲醇－水三元溶剂系统中的保留符合Ｋｏｗａｌｓｋａ所提出的 物理化学保留模型１。但由于模型１没有考虑到化学计量问题，故其结果不够精确。本文在模 型１中引入粘度系数（或介电常数）来定量表示化学计量关系，得到明显优于模型１的模型 ２。鉴于ＨＰＬＣ系统中常以ｌｏｇＫ’表示保留值，本文以ｌｏｇＫ’代替模型１、２中的Ｒｆ值，简化了 计算。
The retention of ferrocene derivatives in tetrahydrofuran-methanol-water ternary solvent systems follows the physicochemical retention model proposed by Kowalska1. However, because model 1 did not consider the stoichiometric problem, the result was not accurate enough. In this paper, the viscosity coefficient (or dielectric constant) is introduced into Model 1 to quantitatively represent the stoichiometry, and Model 2, which is obviously superior to Model 1, is obtained. Since the retention of logK ’is often expressed in HPLC system, this paper simplifies the calculation by substituting logK’ for Rf in models 1 and 2.
