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+.
