Crown Ether-Decorated Magnetic Reduced Graphene Oxide as a Composite Adsorbent for Lithium Ion Recovery from Seawater |
초록 |
A multi-functional composite adsorbent (CE-rGO-Fe3O4) was successfully synthesized for selective Lithium ion (Li+) adsorption. The adsorbent is composed of a Crown Ether (CE) as Li+-specific ionophore, magnetite (Fe3O4) for material recovery and recyclability, and Reduced Graphene Oxide (rGO) as a two-dimensional, high aspect ratio support for CE and Fe3O4. The adsorption experiment at varied Li+ concentrations revealed the Langmuir-type Li+ uptake. The adsorbent is highly selective towards Li+ as compared to other cations present in seawater, such as Na+, K+, Mg2+, and Ca2+. 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. This research was supported by the Basic Science Research Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Science, ICT and Future Planning (2015R1A2A1A15055407) and by the Ministry of Education (No. 2009-0093816). |
