Abstract

PURPOSE: To separate and recover harmful heavy metals easily, by bringing an aqueous solution containing lithium and arsenic into contact with insoluble amorphous hydrous tin oxide or crystalline tin hydroxide, adsorbing the lithium and arsenic, and eluting both separately.
CONSTITUTION: An underground brine or geothermal hot water is used as an aqueous solution containing lithium and arsenic. The aqueous solution is previously adjusted to a pH of about 5W10, and amorphous hydrous tin (IV) oxide or crystalline tin (IV) hydroxide in an amount of about 0.1W5wt% is brought into contact with the adjusted aqueous solution to adsorb the lithium and arsenic. After adsorbing the lithium and arsenic fully, the solid adsorbent is separated from the solution. The separated adsorbent is then brought into contact with a dilute aqueous solution of an acid having a pH ≤5 to dissolve the lithium first. The adsorbent is then washed with water and then brought into contact with an alkali solution having a pH ≥10 to elute the arsenic.
