Lithium Adsorption of various Dilithium Dioxido(oxo)manganese-based Adsorbents |
| 초록 |
Lithium adsorbents were prepared from dilithium dioxido(oxo)manganese (Li2MnO3) byacid treatment using 2.5 N H2SO4 at 75°C for 24 hr. The Li2MnO3 were synthesized by solid-state reaction between Li2CO3 and MnCO3 at 500-700°C. Li+ adsorption capacity (Q) of the adsorbents ranged between 75.65 ± 0.02 and 99.87 ± 0.04 mg Li+/g adsorbent according to elemental analysis and acid-base titration. The BET surface area of the adsorbents increased by 17-56 folds after Li+ leaching. Li+ adsorptions increased with pH increased. Maximum Q of the adsorbents were between 13.06 ± 0.06 and 23.49 ± 0.45 mg Li+/g adsorbent. The highest Q value was obtained from Li2MnO3 fabricated at 500°C. This work was supported by the National Research Foundation of Korea (NFR) grant funded by the Korea goverment (MEST) (No. 2012R1A2A1A01009683 and 2012-0006693). |
