主 题:Actinides Photooxidation Radiochemistry Plutonium Separation
摘 要:Plutonium(Pu)is a key actinide in nuclear industry and is the only element in the periodic table known to date that could exist in four different oxidation states simultaneously in aqueous *** recovery of Pu in nuclear wastes relies greatly on the precise control of its oxidation ***,we introduce a light-driven oxidation approach that could effectively oxidize Pu(Ⅳ)to Pu(Ⅵ)in acidic solutions without the addition of extra chemical *** oxidation proceeds via the reaction of Pu(Ⅳ)with the oxidative species induced by UV light *** approach can help with the separation of Pu from other metals and can be further extended to a biphasic extraction system to achieve green and efficient stripping of Pu from an organic solvent.
