“…On the opposite hand, some commercial resins show much lower sorption capacities applied for the treatment of very acidic solutions. Sorption capacity does not exceed~0.3 mmol U g −1 for Tulsion CH-96 in 4 M HNO 3 solutions [96], 0.49 mmol U g −1 for Purolite A400 at pH 1.9 [22], or 0.71 mmol U g −1 on magnetic phosphine oxide/amino functionalized sorbent at pH 0.5 [97]. At the pH selected for the current study (i.e., pH 4), the sorption performance for PGG@C and PGG@MC (i.e., 1.15-1.28 mmol U g −1 and 22-47 L mmol −1 ) is consistent with the highest values reported in terms of maximum sorption capacity and affinity coefficient for the most efficient alternative sorbents.…”

Phosphorylation of Guar Gum/Magnetite/Chitosan Nanocomposites for Uranium (VI) Sorption and Antibacterial Applications

The development of new materials is needed to address the environmental challenges of wastewater treatment. The phosphorylation of guar gum combined with its association to chitosan allows preparing an efficient sorbent for the removal of U(VI) from slightly acidic solutions. The incorporation of magnetite nanoparticles enhances solid/liquid. Functional groups are characterized by FTIR spectroscopy while textural properties are qualified by N2 adsorption. The optimum pH is close to 4 (deprotonation of amine and phosphonate groups). Uptake kinetics are fast (60 min of contact), fitted by a pseudo-first order rate equation. Maximum sorption capacities are close to 1.28 and 1.16 mmol U g−1 (non-magnetic and magnetic, respectively), while the sorption isotherms are fitted by Langmuir equation. Uranyl desorption (using 0.2 M HCl solutions) is achieved within 20–30 min; the sorbents can be recycled for at least five cycles (5–6% loss in sorption performance, complete desorption). In multi-component solutions, the sorbents show marked preference for U(VI) and Nd(III) over alkali-earth metals and Si(IV). The zone of exclusion method shows that magnetic sorbent has antibacterial effects against both Gram+ and Gram- bacteria, contrary to non-magnetic material (only Gram+ bacteria). The magnetic composite is highly promising as antimicrobial support and for recovery of valuable metals.

“…Various conventional approaches were applied for reclamation of radioactive industrial liquid effluents, for instance, bioprecipitation [7], reductive precipitation [8], ion change [9,10], and adsorption [11][12][13]. Among all these mentioned techniques, adsorption is a talented method for uranium species illumination from wastewater owing to its simplicity, effectiveness, and feasibility [13,14].…”

Uranium (as a hazardous and radioactive element) removal from wastewater requires reliable technology and proper functional materials. Carbon fiber species that are produced from agricultural solid waste can be a proper type of low-cost adsorbents for wide uses in wastewater treatment. In this work, two carbon fiber species labeled CF-RH and CF-SCB were synthesized from two different agricultural wastes, namely, rice husk and sugarcane bagasse respectively. The structural properties of carbon fiber were verified by XRD, FTIR, and Raman, spectroscopy. Both nitrogen-adsorption–desorption BET surface area and TEM were performed to figure out the textural characteristics of the presented sorbents. The charges on surfaces of the fibers were detected via zeta potential analysis. The prepared carbon fibers were applied for uranium removal from aqueous solution by adsorption technique. The acquired data display that the equilibrium time was 240 min. The results of adsorption process are nicely fitted with pseudo-second-order-kinetic and Langmuir isotherm models. The maximum sorption capacity was 21.0 and 29.0 mg/g for CF-RH and CF-SCB, respectively. Sorption thermodynamics declare that adsorption of U(VI) is an endothermic, spontaneous, and feasible process. The picked findings of this study could emphasize high reliability of the introduced adsorbents in efficient tackling of water contaminants.

“…Indeed, leaching methods remain the most used techniques for the extraction (solid->liquid transfer) of metals from low-grade ores. In the liquid phase, the metals may be recovered by precipitation [3], mineral sorbents [4][5][6][7][8], agricultural wastes [9], functionalized composites [10,11], solvent extraction [1,12], activated carbon [13] or carbonized biomass [14], membrane processes [15], impregnated resin [16] or ion-exchange and chelating resins [17][18][19][20][21][22], depending on the composition of the leachates, the concentration of metals, and the flux of the effluent. Usually, sorption processes are preferred for the treatment of dilute solutions.…”

Polyamide (PA6) and hydroxyapatite (n-HAp) have intrinsic sorption properties for metal ions. Their association by melt compounding allows manufacturing a composite material (PA6/n-HAp) efficient for the binding of uranyl and rare earth metal ions (REEs) in acidic solution (in the pH range 2-2.5). The composite shows enhanced sorption capacities (5-7 times) compared with single PA6 material. The structuration of the material slightly improves textural properties but contributes to improve the accessibility and availability of reactive groups (including by size distribution). Metal sorption proceeds mainly through complexation of amide reactive groups as shown by FTIR characterization (modification of the environment of C --O and NH groups) rather than ionexchange/electrostatic attraction. Maximum sorption capacities approach 0.34 mmol U g − 1 , 0.49 mmol Er g − 1 and 0.70 mmol Nd g − 1 : the preference may be correlated to the covalent rather than ionic character of these metal ions. Uptake kinetics are relatively slow (requiring up to 6− 8 h, under selected experimental conditions): the textural properties of the composite (pore size: 2.6 nm) limit the mass transfer properties (though slightly enhanced compared with PA6 precursor). The resistance to intraparticle diffusion constitutes the major con-trolling step for uptake kinetics. Nitric acid is the most efficient eluent for the desorption of loaded metals (ef-ficiency exceeds 94 %); noticeably U(VI) elution is optimal at 1 M HNO 3 concentration, contrary to REEs that require lower concentration (i.e., 0.1 M). Preliminary tests on sulfuric acid leachates of Egyptian ores demon-strate that the sorbent maintains good sorption properties for REEs and U despite the complexity of the solution. The sorbent has a marked preference for REEs, U and Th against base and alkali metals.
