| Popis: | N,N-Dihexylacetamide in toluene was used to extract uranium selectively from an aqueous phase containing 30 elements at 10 or 100 μg l−1 concentrations. After three extractions, the uranium level fell from 119 000 mg l−1 (0.5 M) to less than 3 mg l−1. An inductively-coupled plasma/mass spectrometer (i.c.p./m.s.) was used to determine recoveries of the trace elements in the aqueous phase, which, in most cases, were in the range 90–110%. This combination of liquid-liquid extraction with i.c.p./m.s. offers determinations at the 10 ng g−1 level in uranium for most of the elements studied. |
