Abstract

Uranium was extracted with a 0.15M di-(2-ethylhexyl) phosphate solution in toluene, and directly determined in the organic phase by the liquid scintillation technique. The selection of the optimum conditions of measurement is explained using an established isoamplitude curve, and235U is determined in the presence of small amounts of fission products. The proposed method also allowed the determination of234U in 1 mg of enriched uranium, with a relative error of ±0.52%.
