Research Abstract	Collection of the trace uranium in seawater for resources was investigated by using a emulsion flow liquid-liquid extraction apparatus based on a new idea. The PC-88A and kerosene were selected as extraction reagent, and counter current emulsion flow extractor was developed and operated without any interference of suspended materials in seawater. Uranium more than 90% in 1200 L seawater was collected by the system in conjunction with automatic back extraction apparatus avoiding the saturation of organic phase with uranium extracted, and apparatuses removing interference elements in seawater and oil particles of extraction reagent in waste water.
