Research progress of extraction uranium from seawater

In this paper, the research progress on the separation of uranium in seawater all over the world was discussed. The adsorbent that has oxime group in molecular structure as the chief target of study is prepared in the world at present. The most representative one is amidoxime functionalized polyethylene fiber adsorbent of Japan which is used to semi-industrial experiment. In addition, metal organic frameworks and biological adsorbents prepared recently also have high adsorption capacity to extract uranium in seawater. The research status on the adsorption system from seawater was also introduced. In addition, the expectation on further research in this field was ex- pressed. (authors)
