Lithium Recovery Using Hydrogen Manganese Oxide Adsorbent Derived from Spinel Lithium Manganese Oxide

Lithium recovery from brine is recently attracting significant attention due to increasing industrial demand for energy storage, such as batteries. The lithium was investigated using hydrogen manganese oxide adsorbent. adsorbent HMn2O4 (HMO) derived the spinel (LMO), which synthesized LiOH and MnO2 precursor through reflux method. characterized Scanning Electron Microscopy identify its physical characteristics surface morphology. adsorption capacity toward solution performed an ion exchange process, values were determined Atomic Absorption Spectroscopy (AAS). HMO has a high lithium-ion, 23 mg/g, 10 mg/g desorption. optimum uptake of 44% initial (52 ppm) after 120 minutes contact time. potential large-scale application.
