Interaction between Uranyl Cations and Layered Double Hydroxide Nanoparticles: Implications for Nuclear Wastewater Management

ACS ES&T Water, Journal Year: 2024, Volume and Issue: 4(7), P. 3059 - 3067

Published: June 11, 2024

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.

Polyethyleneimine and Chitosan Incorporated Winter Melon-Derived Biochar Composite Gels for Highly Selective Capture of Uranium(Vi)

Published: Jan. 1, 2024

This work synthesized polyethyleneimine and chitosan modified winter melon-derived biochar (PEI-CTS@WBC) using chemical crosslinking method for uranium(VI) removal. The factors influencing adsorption by PEI-CTS@WBC, including pH, adsorbent dosage, time, temperature, initial U(VI) concentration were explored. material's performance was characterized, the underlying mechanism of removal analyzed various techniques. results demonstrated that PEI-CTS@WBC effectively removed U(VI), achieving a maximum capacity 411.44 mg g-1 at pH 5.0. dynamics studies showed more in line with second-order kinetic model, indicating main process. XPS analysis process primarily due to formation stable complexes N-H, N-C, C-O O-H. research introduction greatly improved effect WBC on U(VI). had high selective characteristics good reusability aqueous solutions. an economical, efficient composite material. These findings provided theoretical basis treatment wastewater contaminated
