“…The crown ether as the host has a certain dipole moment and can interact with the guest ion to coordinate, owing to the existence of electron-donating oxygen atoms. The hole diameter of the crown ether ligand is 1.223-1.534 Å, and the diameter of Li + is 1.22 Å, which matches the hole size, and can completely enter the hole and form a strong electrostatic interaction force with the crown ether oxygen [14]. However, crown ethers usually exist in the form of small molecules in liquid form, and they are usually introduced as ligands into functional groups, so that they are easily connected to the matrix through chemical bonds to form a composite adsorbent with a stable structure [15].…”

Nanofiber membranes were successfully prepared with crown ether (CE) functionalized graphene oxide (GO), chitosan (CS), and polyvinyl alcohol (PVA) by low-temperature thermally induced liquid–liquid phase separation. The physical and chemical properties and adsorption performance of nanofiber membrane were studied through SEM, FT-IR, XRD, and static adsorption experiments. The results show that the specific surface area of the nanofiber membrane is as high as 101.5 m2∙g−1. The results of static adsorption experiments show that the maximum adsorption capacity of the nanofiber membrane can reach 168.50 mg∙g−1 when the pH is 7.0. In the selective adsorption experiment, the nanofiber membrane showed high selectivity for Li+ in salt lake brine. After five cycles, the material still retains 88.31% of the adsorption capacity. Therefore, it is proved that the material has good regeneration ability.
