Title: Sylvie Lours: Innovator in Uranium and Ruthenium Recovery
Introduction
Sylvie Lours is a prominent inventor based in Fontenay-aux-Roses, France. She has made significant contributions to the field of chemical engineering, particularly in the recovery of uranium and ruthenium. With a total of 2 patents, her work has important applications in the nuclear industry.
Latest Patents
One of her latest patents is a process for the determination of uranium (VI) or dialkyl dithiophosphoric acid present in an organic solvent. This innovative process involves adding a dialkyl dithiophosphoric acid or a uranium (VI) salt to the organic solvent, converting all the uranium or dialkyl dithiophosphoric acid into a mixed uranium (VI) - dialkyl dithiophosphoric acid-organophosphorus compound complex. The optical density of the solvent containing the complex is then measured to determine the concentration of the complex and its uranium content. This method has applications in determining traces of uranium in tributyl phosphate obtained from the reprocessing of irradiated fuels.
Another significant patent by Lours is a ruthenium recovery process by solvent extraction. This process focuses on recovering ruthenium from an aqueous nitric solution by extracting it in an organic solvent. The extraction is achieved by contacting the nitric solution with an organic phase that includes an organophosphorous compound with at least one electron donor sulfur atom. This method is particularly useful for recovering ruthenium contained in nitric solutions derived from dissolving irradiated fuel elements.
