Title: Pierre Doutreluigne: Innovator in Plutonium Recovery
Introduction
Pierre Doutreluigne is a notable inventor based in Bagnols/Ceze, France. He has made significant contributions to the field of nuclear chemistry, particularly in the recovery of plutonium. With a total of 3 patents, his work has implications for nuclear fuel reprocessing and environmental safety.
Latest Patents
One of Doutreluigne's latest patents is a method for recovering plutonium (IV) using crown compounds. This invention involves placing an aqueous solution containing plutonium (IV) in contact with at least one crown compound, such as DCH 18C6, which is dissolved in an organic diluting agent like benzonitrile. In cases where the solution contains only traces of plutonium, a crown compound secured to a solid phase, such as silica, can be utilized. The aqueous solution may originate from concentrated solutions of fission products or effluents from irradiated nuclear fuel reprocessing installations.
