The extraction of uranium(IV) from phosphoric acid by mono-(2-ethylhexyl) phosphoric acid in kerosene has been investigated. The effects of extractant concentration, hydrogen ion concentration, temperature, and the synergistic effect of trioctyl phosphine oxide and dibutyl butyl phosphonate on this extraction system have been examined. Based on the extractant dependency and the acid dependency, an ion-exchange mechanism was generally observed and the extracted species were of the type, UH/sub 8n-4/X/sub 4n/, UH/sub 8n-4/X/sub 4n/.TOPO, and UH/sub 8n-4/X/sub 4n/.DBBP. The temperature effect for the extraction reaction has also been studied.
