“…In this aspect, 30 mg of uranium and thorium ion loaded adsorbent was immersed in 50 mL of 0.1 M HCl solution and agitated on a shaker for 3 h. After desorption of uranium and thorium ions, beads were washed with distilled water and collected through the external magnet, dried in a hot air oven at 40 °C for 8 h, and then reused for further adsorption studies. In the acidic medium, hydrogen bonds got weakened between the uranium and thorium ions and MNPs-SA@Cu MOF composite beads and desorption takes place. , It can be seen from Figure a, beads showed the ten adsorption–desorption cycles with a slight decrease in the removal efficiencies of U(VI) (99.99 to 92%) and Th(IV) (97.78 to 89.25%) without the demolition of the beads. Recovery of uranium and thorium ions have also been checked after desorption.…”

Effluent from nuclear power plants, rocks, and minerals contains hazardous radionuclides that adversely affect human health and seriously threaten the environment. To address this issue, simple, economic, and sustainable magnetite nanoparticle loaded sodium alginate copper metal–organic framework composite beads (MNPs-SA@Cu MOF composite beads) have been designed, and their performance has been evaluated under varying conditions of pH, time, adsorbent dose, and initial concentration and have been studied by batch adsorption studies for optimizing the adsorption conditions. In this work, MNPs-SA@Cu MOF composite beads have been prepared in situ for the adsorptive removal of uranium [U(VI)] and thorium [Th(IV)] ions from an aqueous solution. The synthesized MNPs-SA@Cu MOF composite beads were characterized by model analytical techniques like Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, field emission scanning electron microscopy, Brunauer–Emmett–Teller, and thermal gravimetric analysis. Here, 6 mg of adsorbent with 10 mL of 50 mg/L uranium and thorium ion solution at pH 5 was capable of removing the U(VI) and Th(IV) ions with 99.9 and 97.7% removal efficiencies, respectively. The obtained results showed that the adsorption behavior of the adsorbent for U(VI) and Th(IV) follows pseudo-second-order kinetics, and Langmuir isotherm fitted well with a maximum adsorption capacity of 454.54 and 434.78 mg/g, respectively. The adsorption mechanism indicated that electrostatic interaction and hydrogen bonding are the main driving forces for removing the U(VI) and Th(IV) ions. It can be reused for up to 10 adsorption–desorption cycles with minimal loss of removal efficiency. The easy synthesis method of MNPs-SA@Cu MOF composite beads and the high removal efficiency of U(VI) and Th(IV) ions reveal that they can potentially treat radionuclide waste effectively.

“…A comparison of q max values demonstrates that synthesized Cs-BFPA, Cs-BFB, and Cs-BODB exhibit a decent aptitude for uranium adsorption. The sorption capacity of CBASB derivatives (Cs-BFPA, Cs-BFB, and Cs-BODB) for uranium(VI) was significantly higher than those acquired from the literature in Table 3 (Oren et al 2000;Venkatesan et al 2004;Wang et al 2009;Kadous et al 2010;Morsy 2015;Orabi et al 2016Orabi et al , 2020Ali and Nouh 2019;Fouad et al 2019;Xiao-teng et al 2019;Orabi et al 2021). Also, as shown in Table 4, although the sorption capacity of CBASB derivatives resin is lower than some novel adsorbents, e.g., graphene oxide (Sun et al 2015), their regeneration has not been considered.…”

Three new cross-linked chitosan derivatives were yielded through intensification of chitosan with diverse types of bis-aldehydes. The prepared cross-linked chitosan was characterized by FTIR, 1H NMR, XRD, and TGA techniques. TGA indicated an improvement in thermal stability of the cross-linked chitosan compared with pure chitosan. Batch adsorption experiments showed that the three novel cross-linked chitosan bis-aldehyde derivatives possessed good adsorption capacity against U(VI) in the order of BFPA > BFB > BODB (adsorption capacity of the three adsorbents for U(VI) reaches 142, 124, and 114 mg/g respectively) and the adsorption isotherm and kinetic were well described by the Langmuir and the pseudo-second-order kinetic model, respectively. In addition, the prepared cross-linked chitosan bis-aldehyde derivatives were examined as U(VI) catcher from waste solutions. Graphical Abstract

“…The chemical pretreatment methods include TEMPO oxidation, sulfonation, phosphorylation, esterification, cationization, amination, etc. [ 20 , 21 , 22 , 23 ], which can not only increase the adsorption sites of cellulose, but also change the morphology of adsorption materials, thus enhancing the interaction with metal ions [ 24 ]. Among the numerous coordination functional groups, the amidoxime group could combine with many kinds of metal ions under acidic conditions to form stable chelates.…”

Selective extraction of low-concentration thorium (Th(IV)) from wastewater is a very important research topic. In this paper, amidoxime cellulose was synthesized, and its composition and structure were characterized by FT-IR, SEM, XPS, and elemental analysis. The adsorption experiment results showed that the adsorption reaction was a spontaneous exothermic process. When the solid–liquid ratio was 0.12 g/L and the pH value was 3.5, the adsorption percentage of the Th(IV) in water onto amidoxime-functionalized cellulose (AO-CELL) could reach over 80%. The maximum adsorption capacity can reach to 450 mg/g. At the same time, the adsorption selectivity, desorption process and reusability of the material were also studied. The results showed that the AO-CELL had a good selectivity for Th(IV) in the system with Sr2+, Cu2+, Mg2+, Zn2+, Pb2+, Ni2+, and Co2+ as co-ions. In the nitric acid concentration of 0.06 mol/L system, the AO-CELL desorption rate of Th(IV) can reach 95%, and the adsorption rate of Th(IV) in aqueous solution of AO-CELL is still above 60% when the AO-CELL is reused four times. The above results show that the amidoxime cellulose adsorption material synthesized by our research group has good selective adsorption performance for Th(IV) of a low concentration in an aqueous solution and has a good practical application value.
