Abstract
The present disclosure relates, according to some embodiments, to a method for recovery of lithium ions from a lithium-ion containing liquid, the method comprising the steps of coating a nanoparticle with a styrene monomer; polymerizing the styrene monomer to form a polystyrene-coated nanoparticle; attaching a dibenzo-12-crown-4-ether to the polystyrene-coated nanoparticle to form a lithium adsorbing medium; exposing the lithium ion-containing liquid to the lithium adsorbing medium to form a lithium-rich adsorbing medium; and extracting the lithium ion from the lithium-rich adsorbing medium.
Claims10
A method for recovery of metal ions, the method comprising:
- providing a first medium adapted to adsorb the metal ions, the first medium comprising a nanoparticle, the nanoparticle comprising a polystyrene coating and a dibenzo-12-crown-4-ether;
- exposing a solution containing the metal ions to the first medium to form a second medium enriched with the metal ions and a liquid depleted of the metal ions;
- extracting the metal ions from the second medium;
- and
- magnetically separating the second medium from the liquid, wherein the metal ions are lithium ions.
