Purification of uranium-contaminated radioactive water by adsorption: A review on adsorbent materials

Sequestration of Contaminants from Wastewater: A Review of Adsorption Processes

“…Out of the myriad of decontamination methods, adsorption stands out because of the availability of various adsorbents, simplicity of preparation, easy handling, minimal operational expense, high efficiency, fast kinetics, extensive applicability, non-secondary contamination, and easy regeneration capacity of the adsorbents [8]. As the extent of adsorption is measured by suitable adsorbents for specific components, it is necessary to completely interpret the physicochemical aspects of adsorbents and the mechanisms -----associated [9]. The textural properties and the location of active sites influence the adsorption mechanism [10].…”

Synchronously enhanced storage stability and adsorption ability of MXene achieved by grafting polyethylenimine

“…Adsorption materials can mainly be divided into organic and inorganic adsorbents. 9 Diatomite, 10 zeolite, 11 kaolinite, 12 and graphene oxide 13,14 are extensively used as inorganic adsorbents because of their high porosity and large surface area. Organic adsorbents can be classified into natural and artificial organic adsorbents.…”

Enhancing Uranium Removal with a Titanium-Incorporated Zirconium-Based Metal–Organic Framework

“…Among various extraction methodologies developed for uranium capture, the adsorption technique has garnered significant attention due to its cost-effectiveness, straightforward implementation, and impressive efficiency. , To harness the power of this method, the strategic design and fabrication of adsorbents exhibiting stability, rapid kinetics, selectivity, and substantial adsorption capacity serve as fundamental prerequisites . A gamut of adsorption materials, including clays, oxide materials, hydroxyapatite, polymers, graphene oxide, mesoporous silica, carbon materials, and covalent organic frameworks have been explored for uranium separation, − while their applications are often hindered by laborious procedures, sluggish removal rates, and high costs. Metal–organic frameworks (MOFs), as a novel type of porous crystalline materials, have attracted extensive attention due to their expansive surface area, facile tunability, profuse active sites, and ordered pore structure. , These attributes render them exceptional solid-phase adsorbents for radionuclide sequestration, which also facilitates the exploration of structure–function relationships. − So far, numerous strategies have been devised to enhance MOF adsorption performance.…”
