Popis:	This paper chose LiMn2O4 as ion-sieve. In the ion-sieve precursor pickling experiment, the elution effects of hydrochloride, nitric acid and sulfate were compared and hydrochloride was proved the suitable eluent. By changing the acidity of pickling time, the lithium evacuation rate and the manganese solution loss rate basically achieved balance after pickling for 5 h. The static adsorption experiment suggested that when the pH was 12.5 and adsorption time was 30 h, the equilibrium adsorption capacity was 19.71 mg/g.
