Abstract:

A large number of low-concentration uranium containing wastewater are produced during the uranium smelting and refining process, causing serious pollution to the environment. The treatment of uranium containing wastewater by membrane extraction is reviewed in this work. Membrane extraction is a new separation technology combining membrane separation and liquid-liquid extraction. This review aims to summarize the applications of three kinds of membranes(liquid membrane, hollow fiber membrane and polymer inclusion membranes) in the treatment of uranium containing wastewater. Compared with traditional extraction technology, the advantages and limitations of the membrane extraction technology are discussed from the view of application. The application characteristics and mechanism of the membrane extraction are also analyzed. Furthermore, the future development trend of membrane extraction technology is prospected.

Key words: uranium contaminated wastewater, liquid membrane, hollow fiber membrane, polymer inclusion membranes
