제목 |
Mechanochemical synthesis of titanium-lithium manganese oxide composite for the efficient recovery of lithium ions from seawater |
초록 |
In this study, to prevent manganese dissolution from an acid treatment during the extraction of lithium ions (Li+), titanium (TiO2) was mixed mechanically with lithium manganese oxide (Li1.33Mn1.67O4, LMO) by a high-energy milling technique followed by calcination. The milling process ensured high-level chemical homogeneity of metal oxides. The TiO2 imparted stability to the LMO spinel structure and reduced the level of Mn dissolution during the extraction of Li+ using an acid. X-ray diffraction and thermogravimetric analysis confirmed that the amorphous SiO2 was well mixed in the framework of LMO. The adsorbent exhibited excellent selectivity towards Li+, even in the presence of competitive cations with a higher concentration than Li+. |
