Abstract
Disclosed herein are embodiments of a polymer-functionalized particle for using in isolating and extracting solutes, such as rare earth metals, lithium, and the like. The polymer-functionalized particles exhibit strong resistance to agglomeration and degradation even in high ionic strength and/or temperature environments. A post-particle synthesis method for making the polymer-functionalized particle is disclosed, along with a magnetic separation device and that can be used in system embodiments to facilitate use and regeneration of the polymer-functionalized particles in solute extraction.
Claims15
A polymer-functionalized particle, comprising:
- a single magnetic core;
- a shell surrounding the single magnetic core, wherein the shell comprises a metal-organic framework material;
- and
- a polymer component that substantially surrounds the shell and the single magnetic core;
- wherein the polymer component comprises a functional group selected from a sulfonate group, an ester group, an aldehyde group, an amine group, or an amide group.
