Abstract�� Research and development of efficient adsorbents are the key to lithium extraction from seawater and brines with high ratio of magnesium to lithium,and the most promising adsorbents for industrial application now are lithium manganese oxide ion-sieves.In this paper,the influences of synthetic conditions on the structures and adsorption properties of lithium manganese oxide ion-sieves were discussed,and the adsorbents which were verified to have high capacity could be applied to seawater and brines with different ratios of magnesium to lithium and different lithium concentrations.The highest adsorption capacity could achieve 41.02 mg/g,and its solution-loss rate of manganese was 3.06%.Furthermore,dynamic simulation experiments on lithium adsorption were carried out,which laid a foundation for the application research on lithium extraction from seawater and brines with adsorbents synthesized in this paper.
