Title:
LITHIUM ADSORBING AGENT AND METHOD FOR PRODUCING THE SAME, AND METHOD FOR COLLECTING LITHIUM
Document Type and Number:
Japanese Patent JP3937865
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an adsorbing agent which practically adsorbs and collects lithium contained in sea water or water in watery environment such as geothermal hot water in a very small amount and has excellent selective adsorption of lithium at high adsorption speed and with large adsorption capacity, and is chemically stable and is repeatedly adsorbed/desorbed, provide a method for producing the same, and a method for collecting lithium using the same.
SOLUTION: This lithium adsorbing agent is composed of a λ-shaped manganese oxide obtained from a spinel lithium manganese oxide through the elution of lithium by acid treatment. The method for producing the adsorbing agent comprises firing manganese oxide or lithium hydroxide so as to obtain the spinel lithium manganese oxide, and eluting lithium therefrom through the acid treatment.
