Beschreibung
Zusammenfassung:	Disclosed a method for the preparation of granular sorbent based on LiCl.2Al(OH)3.nH2O for lithium recovery from lithium-containing brines, comprising production of a powder of LiCl.2Al(OU)3.nH2O (DUAL-Cl) from aluminum chloride solution comprising lithium, separation of the powder DUAL-Cl from the obtained solution by centrifugation with further removing the excess LiCl, drying of the powder DUAL-Cl; and, granulation of the powder DUAL-Cl with the addition of chlorinated polyvinylchloride and a organochlorine solvent to obtain the granular sorbent based on LiCl.2Al(OU)3.nH2O; wherein the aluminum chloride solution comprising lithium is prepared by dissolving crystalline hydrate of hexaaqua aluminum chloride in aqueous solutions comprising lithium in the form of LiCl, Li2CO3, or LiOH.H2O or mixtures thereof, and concentration of aluminum chloride in the solution is 45-220 kg/m3.
