摘要
The present invention relates to a method of extracting manganese in a process of collecting lithium in seawater and a method of manufacturing adsorbents for collecting lithium in seawater. The present invention provides the method of extracting manganese in the process of collecting lithium in seawater comprising: a step of adsorbing lithium in seawater using adsorbents consisting of manganese oxide; a step of obtaining a lithium desorption solution by desorbing lithium adsorbed on the absorbent with an acid solution; and a step of collecting manganese ions contained in the lithium desorption solution through reaction formula 1.
