Abstract
The use of the fluorimetric analysis method in phosphoric medium proved that this method is very sensitive for detecting Uranium traces (10 E-10 M). The dosing can be carried out after a simple calibration of the device and without calling for the addition techniques. The interference of most organic matters is eliminated by the 337 nm exciting radiation. The inhibition of the fluorescence induced by anions and cations is generally resolved by a simple dilution. The nitrates that have a harmful effect on the Uranium fluorescence have been eliminated by successive evaporations. This method, as it has been improved in this work, is applied to the study of U-6 reduction by metallic Iron and Fe-2 in orthophosphoric acid medium in case the absorption spectrophotometry becomes inoperative. 37 figs., 14 tabs., 50 refs. (author).
