“…The use of crown ethers (CEs) for the host–guest selective binding and recovery of metal ions in various media has continued to evolve over the years. − The unique structure of the CEs often drives their complexation with the metal ions, leading to strong ion–dipole interactions. The strength and stability of the complexes depends on the crown pore size, the size and charge of the metal ions and the nature of the solvating medium. , With the emergence of the nanopore technology, single-ion channels of CEs have been created on several two-dimensional (2D) materials for various applications ranging from the recovery of metal ions in aqueous media − to energy storage applications. , The incorporation of the CEs afforded the creation of hybrid 2D-CE materials, which retain both the unique features of the 2D materials such as high carrier mobility and high surface area and the charge polarization within the crown cavities for the selective recovery of various ions.…”

“…Paul et al [8] reported the catch-release fluorescent dosing and recycling of silver ions on an anthraceneappended CE and demonstrated the practical utilization of such systems in molecular communication. Falaki and co-workers [9] reported the selective recovery of silver and lead ions from singlestream solutions on supported liquid membranes loaded with 18-crown-6 materials. The extraction of silver, cesium, strontium, and other metal ions in fluorinated diluents containing CEs was reported by Smirnov et al [10] Fissaha and co-workers [11] demonstrated the recovery of silver ions on hydroxylated thio-CEs with various cavity sizes and achieved excellent uptake of 124 -179 mg g −1 within 24 h. While the thia-CEs have achieved remarkable results, their complex synthesis protocol and the time required to achieve maximum uptake make them impractical for real analysis where abundant competing ions co-exist.…”

Silver recovery from sustainable sources such as seawater and e‐waste is critical for the conservation of land‐based resources and the reduction of the environmental impacts of e‐waste disposal. However, the abundance of competing metal ions in seawater and in e‐waste makes the recovery extremely challenging. Thus, to effectively capture silver ions under these conditions, the designing of materials with high selectivity, sufficient binding sites, and low affinity to competing metal ions is vital. Herein, we report the design and synthesis of a 3D‐like Schiff‐bridging crown‐based material named AC5, for the selective recovery of Ag+ ions. Through this design, a significant enhancement in the silver ion recovery was achieved with an excellent removal efficiency of up to 99.9%, and a tremendous increase in selectivity of 400 000 – 900 000% when compared to the metal ions (Li+, Na+, K+, Mg2+, and Ca2+) found in seawater, and the heavy metal ions (Cu2+, Cd2+, Ni2+, and Pb2+) found in electronic wastes. Density functional theory and molceular dynamics simulations revealed that the structural geometry of AC5 favors high charge transfer, lowered global hardness, and enhanced ion‐dipole attractions toward Ag+ ions, making the material an excellent candidate for the efficient recovery of silver from desalination brine and spent silver resources.

Membrane technology with advantages such as reduced energy consumption due to no phase change, low volume and high mass transfer, high separation efficiency for solution solutions, straightforward design of membranes, and ease of use on industrial scales are different from other separation methods. There are various methods such as liquid–liquid extraction, adsorption, precipitation, and membrane processes to separate contaminants from an aqueous solution. The liquid membrane technique provides a practical and straightforward separation method for metal ions as an advanced solvent extraction technique. Stabilized liquid membranes require less solvent consumption, lower cost, and more effortless mass transfer due to their thinner thickness than other liquid membrane techniques. The influence of the electrostatic properties, derived from the electrical field, on the ionic transport rate and extraction recovery, in flat sheet supported liquid membrane (FSLM) and electro flat sheet supported liquid membrane (EFSLM) were numerically investigated. Both FSLM and EFSLM modes of operation, in terms of implementing electrostatic, were considered. Through adopting a numerical approach, Poisson-Nernst-Planck, and Navier–Stokes equations were solved at unsteady-state conditions by considering different values of permittivity, diffusivity, and viscosity for the presence of electrical force and stirrer, respectively. The most important result of this study is that under similar conditions, by increasing the applied voltage, the extraction recovery increased. For instance, at EFSLM mode, by increasing the applied voltage from $$10 $$ 10 to $$30 {\text{V}}$$ 30 V , the extraction recovery increased from $$53$$ 53 to $$98\%$$ 98 % . Furthermore, it was also observed that the presence of nanoparticles has significant effects on the performance of the SLM system.
