摘要

使用尖晶石锂锰氧化物（Li1.6Mn1.6O4）从沉积盐水中提取锂具有挑战性，因为存在溶解的有机化合物，导致锰的还原和损失。在吸附剂表面覆盖一层7.5 nm的二氧化锆层，减少了约50%的锰损失，同时对吸附剂的吸附能力和选择性没有实质性影响，从而提高了吸附剂的使用寿命。

Lithium extraction using zirconium oxide coated lithium manganese oxide ion-exchange adsorbents†

Lithium extraction from sedimentary brines using spinel lithium manganese oxide, Li_1.6Mn_1.6O₄, is challenging because of the presence of dissolved organic compounds, resulting in manganese reduction and loss. Coating the sorbent with a 7.5 nm layer of zirconium dioxide decreased manganese loss by approximately 50%, while not substantially impacting its adsorption capacity and selectivity, thereby increasing its usable life.
