METHOD FOR EXTRACTING MANGANESE IN SYSTEM OF RECOVERING LITHIUM IN SEA WATER AND MEHTOD FOR MANUFACTURING ADSORBENT FOR RECOVERING LITHIUM IN SEA WATER

摘要

The present invention relates to a method for extracting manganese (Mn) during a process of recovering lithium (Li) from seawater and a method for preparing an adsorbent to recover Li from the seawater using the same. The method for extracting Mn during the process of recovering the Li from the seawater includes: adsorbing Li in the seawater using the adsorbent including Mn oxide; acquiring Li desorption solution by desorbing the Li adsorbed onto the adsorbent using an acid solution; and recovering Mn ions contained in the Li desorption solution through following equation 1, (2Mn^2+) + Ca(OCl)_2 + 2H_2O - 2MnO_2 + (4H^+) + CaCl_2.
