Polyvinyl alcohol (PVA) with lithium ion sieves (LIS): A novel reusable lithium adsorbent foam prepared via cryo-desiccation and chemical cross-linking |
| 초록 |
Composite polyvinyl alcohol (PVA) with H1.6Mn1.6O4 (HMO) foams were produced via cryo-desiccation method as lithium (Li+) adsorbents. SEM-EDS and FE-EPMA revealed homogenous HMO distribution in the 3D network of the foam. Hydrophilicty of the PVA-HMO foams facilitated good contact between the Li+ solution and the adsorbents, minimizing Li+ adsorption loss of the foams relative to the HMO powder. Adsorption performance improved at high HMO loading of 250%. Further increase in loading (300%) resulted in poor mechanical stability. In a simulated seawater, PVA-HMO foam preferentially adsorbed Li+ over other cations. This work was supported by the National Research Foundation of Korea (NRF) grant funded by the Ministry of Science, ICT & Future Planning (No. 2012R1A2A1A01009683) and the Ministry of Education (No. 2009-0093816). |
