FIELD: analytical methods.
SUBSTANCE: method comprises hydrolysis of uranium hexafluoride sample and sodium nitrite-mediated reduction of bromates into bromides, whereupon samples are formed by selective precipitation of bromide ions on thin layer of as-precipitated silver chloride followed by washing of precipitate with weak nitric acid solution and fixation thereof with polymer film, after which content of bromine is found from intensity of fluorescent emission in formed test and reference samples.
EFFECT: enabled reliable determination of bromine at a level thereof about 5 ppm based on the uranium content.
