萃取技術的發展趨向(下篇)

The Trend on the Future Development of Extraction Technlogy (Part II)

摘要


液膜萃取是一新的分離技術,其萃取原理與傳統萃取相同但過程有異,係利用偶合傳送機構將溶質由低濃度區傳送至高濃度區域而達到分離、濃縮之目的,非常適合低金屬含量溶液之分離濃縮。液膜可分為乳狀液膜和支撐液膜。本文就液膜萃取之原理、過程、應用及今後研究發展方向以及萃取對社會經濟層面之潛能詳加討論之。

Liquid membrane extraction is a new separation technology. The extraction principle is the same as conventional solvent extraction, however, the extraction steps are different. The solute can be transported from low concentration zone to high concentration zone via coupled transport process. It is a promising technology for separating and concentrating metal species from dilute solutions. Liquid membrane can be divided into emulsion liquid membrane and supported liquid membrane. This report discusses the liquid membrane extraction principle, steps, applications and also projects to the future research and development.
