FIELD: production of inorganic sorbents. SUBSTANCE: sorbent is produced by electrochemical dissolving of aluminium in 0.5-3.0 M solution of lithium chloride at current density of 8-20 A/sq.dm for 1-2 h. Produced precipitate is separated by filtering. Sorbent is prepared for sorption process by its treatment with water with intensive stirring to remove a portion of lithium from sorbent matrix. EFFECT: higher efficiency. 1 tbl
