Abstract
Process for the determination of traces of uranium in solution by the spectrofluorimetry method. The fluorescence of the uranium molecules in the solution is excited by a pulsed laser shot. The exponential decay curve of this fluorescence is studied for a given wavelength. The value F.sub.O of said same fluorescence is deduced at the end of each laser pulse and is compared with the value F'.sub.O obtained for a standard uranium solution and containing a known uranium quantity.
