Abstract
Disclosed are a composite nanofiber membrane for the adsorption of lithium, a method for preparing the same, and a lithium recovery apparatus and method using the same. The composite nanofiber membrane for the adsorption of lithium is immobilized with manganese oxide selectively adsorptive of lithium. The composite nanofiber membrane for lithium adsorption exhibits high selectivity for lithium ions and allows for the rapid and easy diffusion of lithium ions through interstitial spaces of the adsorbent. Particularly, the lithium recovery apparatus using the composite nanofiber membrane for lithium adsorption is able to effectively adsorb lithium ions dissolved in seawater in a selective manner within a short period of time, thus reducing the time taken for the adsorption process.
