液膜分离技术及其在铂族金属分离中的应用

Liquid membrane technique and its application to the separation of platinum metals

从液膜分离机理、铂族金属乳状液膜分离技术和支撑液膜分离技术 3个方面对液膜分离技术及其在铂族金属分离中的应用进行了研究和讨论。由于液膜分离技术将萃取、反萃取融合于一体 ,具有较高的传质速率和通量 ,较高的选择性、分离效率和浓缩倍数 ,以及操作简单等特点 ,因此它在铂族金属分离中的研究与应用日益受到人们的重视 ,为铂族金属分离提供了一条新途径。

The liquid membrane technique and its application to the separation of platinum metals were discussed in three aspects including the separation mechanism of liquid membrane,platinum metals separation by emulsion and supported liquid membranes.Because it has the advantages of combination of extraction and back extraction,higher mass transportation speed and throughput,higher selectivity,higher sparation efficiency and concentration ratio and easy to operate,the application of liquid membrane to the separation of platinum metals has attracted the attention of the researchers.This technique will provide a new method for the separation of platiunum metals.
