    摘要
  • 摘要: 通过ＨＰＬＣ结合旋光光度定量的方法，探讨了流动相添加剂β－环糊精及其２，６－二甲基衍生物的吸附性质。结果表明β－环糊精在ＯＤＳ固定相上不吸附，而其２，６－二甲基衍生物则呈典型的单分子层吸附。

     

    Abstract: The adsorption characteristics of β-CD and its 2, 6-dimethyl derivative as mobile phase additives were examined by HPLC chromato graphic methods associated with a polarimetric method for quantification. Results showed that the β-CD does not adsorbe onto the ODS stationary phase but its 2, 6-dimethyl derivative produces a typical Langmuir′s isotherms of a monolayer adsorption.
