Rapid determination of uranium in natural waters by thermal emission mass spectrometry. [For Uranium Resources Evaluation Program]
A method has been developed to rapidly analyze natural water samples for part-per-trillion (ng/l) concentrations of uranium using a custom-built thermal-emission mass spectrometer. The filtered water sample is spiked with /sup 233/U as an internal standard and extracted with a 2 percent solution of TOPO (trioctylphosphine oxide) in carbon tetrachloride. An aliquot of the organic phase is evaporated and the uranium in the residue extracted with aqueous ammonium carbonate. A 5-..mu..l aliquot is taken and dried on a flat rhenium ribbon filament and inserted into the mass spectrometer. A uranium concentration of 3 ng/l will yield a count rate greatermore »
