MATERIAL AND METHOD FOR EXTRACTING LITHIUM FROM BRINE

摘要

The present invention relates to a material and method for adsorbing and separating lithium ions from brine. The material of the present invention is prepared by covalently bonding various solid carrier material surface-modified functional groups with a corresponding crown ether structure. The material of the present invention can be used to separate lithium ions from brine, will not change the adsorption effect due to the change of solid carrier material, and will not cause the other components of the solution to change. The present invention has a low cost, wide application scope, quick adsorption speed, good selectivity and recyclability.
