Abstract
In this paper, the wet mixing method was introduced to prepare spinel lithium manganese oxide (LMO) with $Li_2CO_3$ and $MnCO_3$. The physical properties of the resulting lithium manganese oxide were characterized by the XRD and SEM. The adsorption properties of LMO for $Li^+$ were investigated by batch methods. The maximum adsorption capacity of lithium was calculated from Langmuir isotherm and found to be 27.25 mg/g. The LMO are found to have a remarkable lithium ion-sieve property with distribution coefficients ($K_d$) in the order of $Ca^{2+}$ < $K^+$ < $Na^+$ < $Mg^{2+}$ < $Li^+$, which is promising in the lithium extraction from seawater.
