Synthesis of Novel Hierarchical Rod-like Mg–Al bimetallic oxides for enhanced removal of uranium (VI) from wastewater

Selective Adsorption of Hazardous Substances from Wastewater by Hierarchical Oxide Composites: A Review

“…However, the reason for the higher adsorption tendency of TiO2 to Zn 2+ than Cu 2+ is unknown. Zhang et al presented a hydrothermal synthesis of hierarchical rod-like mesoporous Mg-Al bimetallic oxides (Mg/Al-BOs) with a high specific surface area of 472.4 m 2 •g −1 and high adsorption capacity, selectivity, and reusability for U(VI) uptake via both surface complexation and electrostatic interaction [75]. The oxygen-containing groups on the surface of Mg/Al-BOs play significant roles in the U(VI) adsorption in addition to the electrostatic attractions, for which the complexation process could be described as follows:…”

Protocol for extraction, characterization, and computational analysis of uranium from seawater

“…Implementation of suitable design strategy for U selective materials as adsorbents is required for separation and recovery of Uranium from seawater. This initiated early work on adsorbent technologies involving inorganic materials, like Mg-Al bimetallic oxides (Mg/Al-BOs), 3 amidoximated silver-silica core-shell nanoparticle (Ag@SiO 2 -AO), 4 magnetic nanoparticles, 5 mesoporous silica materials. 6 The developmental stage of UES is dominated by oxime functionalized materials, i.e., polymeric materials (OxF), 7 porous organic polymers (POPs), 8 porous aromatic frameworks (PAFs), 8 synthetic organic polymers, 9 biopolymers, 10 porous carbonaceous adsorbents, 11 ionic liquids, 12 graphene oxides, 13 grafted fibers 14 etc.…”

One-pot synthesis of a graphene oxide-supported TixAl1−xOy-based material modified with amidoxime for highly efficient uranium(vi) adsorption

“…12 Meanwhile, alumina oxide is one of the most common metal oxides, which is widely used in doping materials owing to its excellent uranium adsorption performance and physicochemical properties. 13 Therefore, the oxygen surface affinity of titanium-based materials for uranium can be improved by doping aluminum atoms to form bimetallic oxides. 14 The dispersity of adsorbents can be improved by doping graphite oxide which is based on the fact that a two-dimensional structure in the space of graphite oxide can prevent the aggregation of materials loaded on its surface.…”
