제목 Lithium Adsorption and Selectivity Studies using Crown Ether-functionalized Magnetic Graphene Oxide
초록 A composite adsorbent (CE-GO-Fe3O4) was synthesized and used as lithium ion (Li+) adsorbent. The composite is composed of a crown ether (CE) as Li+-specific ionophore, magnetite (Fe3O4) for its easy separation and recyclability, and graphene oxide (GO) as support of the CE and Fe3O4. The adsorption experiment was conducted at varied Li+ concentrations. Results reveal the Langmuir-type Li+ uptake of the CE-GO- Fe3O4. The adsorbent was highly selective towards Li+ as compared to other cations such as Na+, K+, Mg2+, Ca2+ and Sr2+.  It can be easily separated via external magnet and re-used. Overall results demonstrate the suitability of CE-GO-Fe3O4 for long-term Li+ adsorption application.
