迁移机理对以伯胺为载体的乳状液膜分离钒(Ⅴ)的影响

Influence of the Transport Mechanism on the Separation of Vanadium(Ⅴ)in Liquid Surfactant Membrane with Primary Amine as Carrier

本文主要研究了以伯胺为载体,以上胺N_(205)为表面活性剂,煤油为溶剂,Na_2CO_3作内相试剂的乳状液膜分离钒的迁移机理,以及对分离的影响。经一次液膜处理,钒(V)的浓度可由500ppm 降至5ppm 以下。三种不同类型的实验,分离效果均很好。

The transport mechanism on the separation of vanadium in liquid membrane with primary amine as a daffier,polyamine N-205 assuffactant,Kerosene as solvent,Na_2CO_3 as inner phase have been inve-stigated,and the effect of different transport mechanism on the separa-tion of vanadium have been examined.The results of vanadium removaltests show that the vanadium concentration in feed solution can bereduced form 500 ppm to less than 5 ppm.
