Abstract  

A selective and quantitative extraction method for uranium(VI) in presence of aqueous 20% lithium nitrate solution (pH 3) using 0.1M Adogen-464 (a quaternary ammonium salt) in chloroform medium, has been described. Uranium was subsequently determined by spectrophotometric method. The effects of different parameters on the extraction behaviour are reported. The method was applied in the trace determination of uranium in few ores.
