Abstract:Effective uranium (U) capture is required for the remediation of contaminated solutes associated with the nuclear fuel cycle, including fuel reprocessing effluents, decommissioning, or nuclear accident cleanup. Here, interactions between uranyl cations (UO 2 2+ ) and a Mg−Al layered double hydroxide (LDH) were investigated using two types of uranyl-bearing LDH colloids. The first (ULDH) was synthesized by coprecipitation with 10% of Mg 2+ substituted by UO 2 2+ . Alternatively, UO 2 2+ was added to a neoformed… Show more
