Efficient adsorption of low-concentration uranium from aqueous solutions by biomass composite aerogel

Adsorbents for the Uranium Capture from Seawater for a Clean Energy Source and Environmental Safety: A Review

“…More interesting, Fk-AO represents a higher selectivity ion presence of the other interfering ions and the salinity is 35 g/L. 219 …”

“…More interesting, Fk-AO represents a higher selectivity ion presence of the other interfering ions and the salinity is 35 g/L. 219 With the advancement in technology, extensive studies on amidoxime-based adsorbents concluded the amidoximation process involves hydroxylamine hydrochloride and postalkali treatment makes the overall process difficult. Recently, phosphate-based polymers gained interest in uranium extraction due to low toxicity and environmental friendliness.…”

“…This preparation method not only prepares the material for uranium extraction adsorbent but also decreases the garbage impact of feathers in the environment. More interesting, Fk-AO represents a higher selectivity ion presence of the other interfering ions and the salinity is 35 g/L …”

“… 217 P-Chitosan showed an adsorption capacity of 54.6 mg/g by two ligand donations for uranium adsorption. 218 Recently Pu et al 219 used biomass-based aerogel (Fk-AO) prepared from feather keratin (Fk) for sustainable extraction of uranium from seawater with a high adsorption capacity of 990.10 mg/g due to a high surface area. In addition, Fk-AO adsorbent is prepared on a large scale and could be used for practical application in large anounts of seawater.…”

Enhanced uranium extraction from seawater: from the viewpoint of kinetics and thermodynamics

“…Terrestrial uranium is the primary global source of uranium fuel, but the global mineable reserves are quite limited. 15,16 Seawater is a significant and abundant source for extraction of uranium in a stable complex called Ca 2 [UO 2 (CO 3 ) 3 ]. 17 This proposed resource could potentially address the current energy crisis and ensure future uranium supplies, potentially fulfilling global demand for 10 000 years through cost-effective recovery techniques.…”
