Clicking Crown Ether with Magnetic Graphene Oxide as a Composite Adsorbent Material for Selective Lithium Recovery from Seawater |
| 초록 |
A dual-functional composite adsorbent (CE-rGO-Magnetite) was successfully synthesized and used for selective Lithium ion (Li+) recovery. The adsorbent is composed of a Crown Ether (CE) as Li+-specific ionophore, Magnetite for a magnetic-responsive material, and Reduced Graphene Oxide (rGO) as a two-dimensional, high aspect ratio support for CE and Magnetite. The adsorption experiment conducted 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. It can be easily separated via external magnet and re-used. Overall results demonstrate the suitability of CE-GO-Magnetite 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). |
