METHOD FOR EXTRACTING MANGANESE IN A PROCESS OF COLLECTING LITHIUM IN SEA WATER AND A METHOD FOR MANUFACTURING AN ADSORBENT FOR COLLECTING LITHIUM IN SEA WATER USING THEREOF, CAPABLE OF RECOVERING A LOSS OF A MANGANESE OXIDE AGAIN

摘要

PURPOSE: A method for extracting manganese in a process of collecting lithium in sea water and a method for manufacturing an adsorbent for collecting lithium in sea water using thereof are provided to recover a loss of a manganese oxide again generated in a process of collecting lithium in sea water by using a manganese oxide.;CONSTITUTION: A method of extracting manganese in a process of collecting lithium in sea water comprises the following steps: lithium in sea water is absorbed by using an adsorbent consisting of a manganese oxide; a lithium desorption solution is obtained by a desorption of lithium absorbed in the adsorbent by using an acidic solution; and a manganese ion included in the lithium desorption solution is collected through below equation 1.
