液膜除酚中膜相与内相界面张力的研究

Study on Interface Tension Between Liquid Membrane Phase and the Encapsulated Phase in the Process by Liquid Membrane to Remove Phenol

本文测定了液膜除酚中膜相与内相的界面张力,发现内相中存在酚钠时,两相界面张力值降低,这表明在相界面上存在酚钠的吸附。还发现,内相中氢氧化钠的浓度对两相界面张力也有影响.当氢氧化钠从0增至1%时,界面张力随之减小,当氢氧化钠从1%继续增至5%时,界面张力却随之增加。本文对产生这些现象的原因,进行了初步探讨。

The interface tension between the liquid membrane phase and the encapsulated phase is measured. It is found that existence of pho Na in the encapsulated phase decreases the interface tension. This phenomenon shows that pho Na adsorbs on the interface. The relation between the interface tension and the encapsulated phase NaOH concentration is discovered too. When NaOH concentration increase from 0 to 1%, interface tension decreases. When NaOH concentration increases from 1% to 5%, interface tersion increases. In this paper, these phenomena are discussed.
