Effective uranium (U) capture is required for the remediation of contaminated solutes associated with nuclear fuel cycle, including reprocessing effluents, decommissioning, or accident cleanup. Here, interactions between uranyl cations (UO22+) and a Mg–Al layered double hydroxide (LDH) were investigated using two types uranyl-bearing LDH colloids. The first (ULDH) was synthesized by coprecipitation 10% Mg2+ substituted UO22+. Alternatively, UO22+ added to neoformed obtain second colloid (LDHU). In both LDHU ULDH systems, schoepite (UO2)8O2(OH)12·12H2O, formed. presence U significantly reduced size compared reference colloid. Surface charge aggregation colloids in NaCl, Na2CO3, Na2SiO3, Na3PO4 solutions that are often present wastewaters. Aggregation Na2SiO3 promotes restabilization. While cation not incorporated into structure, it influences nanoparticle growth addition imparting modified surface properties affect aggregation. This has implications radioactive waste disposals, where LDH, which can also incorporate variety other radionuclides, used remediation.
