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 in the process of recovering lithium in seawater, and a method for producing an adsorbent for recovering lithium in seawater using the same, comprising the steps of: adsorbing lithium in seawater using an adsorbent composed of manganese oxide; Desorbing lithium adsorbed on the adsorbent using an acidic solution to obtain a lithium desorbing liquid; And recovering manganese ions contained in the lithium desorbing solution through the following reaction formula (1): (1) A method for extracting manganese in the process of recovering lithium in seawater may be provided. [Reaction Scheme 1] 2Mn ²⁺ + Ca (OCl) ₂ + 2H ₂ O - 2MnO ₂ + 4H ⁺ + CaCl ₂
