Studies on the Interfacial Properties of Liquid-Liquid Extract ion(Ⅲ)--Interfacial Properties of Primary Amine N1923 in the Extraction Systems

本文报道了伯胺N_(1923)的液-液界面吸附特性参数,讨论了N_(1923)的界面吸附特性与其萃取性能的关系。

The iaterfacial adsorption characteristics of primary amine N_(1923) in liquid-liquid extraction systems have been studied. It may be concluded from the experimental results that N_(1923) is adsorbed at the interface in the form of single-molecule. The adsorbability depends on the temperature and the nature of diluents. The experimental results showed that the weaker the polarity of diluent, the stronger the adsorability, and the higher the temperature, the weaker the adsorability. The influence of the aqueous medium concentration on the interfacial adsorption characteristics is not very obrioas. The relation between the adsorption properties of N1923 and its extractability also discusied.
