摘要： 通过对界面吸附特性参数的测定,推断HEH(EHP)以单分子状态吸附于液-液界面。吸附能力的强弱与稀释剂性质及温度有关。两液相极性差别越大,界面吸附能力越强。温度越高,吸附能力越弱。本文还讨论了HEH(EHP)的界面吸附与其萃取性能、相间分配等关系。

Abstract: From the interfacial properties of the titled systems,it may be concluded that HEH(EHP) is adsorbed at the interface in the form of single molecule.The adsorability depends on the temperature and. the nature of diluents.It is shown that the greater the difference in polarity between two phases, the stronger the interfacial adsorbabilityis, and the higher the temperature, the weaker the adsorbability is. The relation between the adsorptive properties of HEH(EHP) and its extractability has also been discussed in this paper.
