“…Taking into account the obtained results, the anion exchange resin, based on the enhanced VBCco-DVB copolymer modified in MV-field, revealed great adsorption capacity (303 mg Re g −1 ), but, most important, the resin revealed a 200-fold greater selectivity toward Re(VII), as compared to excess of Mo(VI), V(V), and Cu(II). This allowed for proposing a solution for the hydrometallurgical challenge of separating Re from Mo [31][32][33][34][35][36]. The activity involving new IX and chelating materials for hydrometallurgy was also aimed on the resins for the recovery of Au from wasted electric and electronic equipment (WEEE).…”

The rapidly increasing demand for technologies aiming to resolve challenges of separations and environmental protection causes a sharp increase in the demand for ion exchange (IX) and chelating polymers. These unique materials can offer target-selective adsorption properties vital for the removal or recovery of harmful and precious materials, where trace concentrations thereof make other techniques insufficient. Hence, recent achievements in syntheses of IX and chelating resins designed and developed in our research group are discussed within this mini-review. The aim of the present work is to reveal that, due to the diversified and unique physiochemical characteristics of the proposed materials, they are not limited to traditional separation techniques and could be used in multifunctional areas of applications, including catalysis, heat management, and biomedicine.

“…Several methods, such as ion exchange, 5,6 solvent extraction, 7,8 reduction–immobilization 9,10 and adsorption, 11,12 have been explored to separate TcO 4 − from wastewater. Various ion exchange resins are used as adsorbents for TcO 4 − capture, but poor irradiation stability and slow kinetics seriously limit their widespread application.…”

BACKGROUNDIn this study, a defective biochar with honeycomb‐like porous structure (BC‐PH) was successfully prepared by the activation of pristine biochar derived from bamboo shoot shell with the chemical reagent KOH, and was applied to selectively separate ReO4− (a chemical analogue for radioactive TcO4−) from acidic solutions.RESULTSThe diffusion, mass transfer and recovery for ReO4− could be significantly improved by the large specific surface area (SBET, 2412 m2 g−1) and high total volume (Vtot, 1.26 cm3 g−1) of BC‐PH. The influence of adsorbent dosage, system pH and coexisting ions with different valence states on the adsorption capability and selectivity of BC‐PH toward ReO4− was systematically investigated. BC‐PH exhibited high adsorption capacity and selectivity for ReO4− with a maximal sorption capacity (qm) of 73.11 mg g−1 at initial pH 2. By applying an analysis of kinetics and isotherm adsorption studies, the liquid film diffusion was verified to be the primary rate‐controlling step for the sorption of ReO4− and the multilayer adsorption process occurred on the heterogeneous surface of BC‐PH. Besides, the recovery of ReO4− using BC‐PH occurred in an exothermic and spontaneous manner according to thermodynamic analysis. Furthermore, an investigation of the adsorption mechanism suggested that pore filling and electron donor–acceptor interaction were mainly related to the removal of ReO4−.CONCLUSIONThese results suggest that BC‐PH has great potential for the application of TcO4− separation in consideration of its high adsorption capacity and selectivity. © 2024 Society of Chemical Industry (SCI).

A novel nanocomposite (TNTs-FeS) was developed by anchoring ferrous sulfide (FeS) nanoparticles immobilized on titanate nanotubes (TNTs) by hydrothermal method to remove U(VI) and Re(VII) from aqueous solution, and the removal mechanism and efficiency were examined. The experimental results showed that the TNTs can effectively improve the dispersibility and stability of FeS. The environmental conditions, including initial solution pH, initial concentration, equilibrium time, and dosage, played an important role in the remediation process, which can affect the immobilization efficiency significantly. The maximum quantity removal of U(VI) and Re(VII) was 291.67 and 226.23 mg/g at pH of 6.0 and 12.0. The adsorption kinetics and the equilibrium isotherms of U(VI) and Re(VII) all fitted well with the pseudo-second-order model (R 2 > 0.99) and the Freundlich model (R 2 > 0.99). The main mechanism of removal by TNTs-FeS was electrostatic attraction, chemical reduction, and surface complexation. Thus, TNTs-FeS composites exhibited a high potential to remove U(VI) and Re(VII) heavy metal ions from the surface and groundwater.
