TREATMENT PROCESS OF AQUEOUS SOLUTION CONTAINING ANTIMONY

摘要

PROBLEM TO BE SOLVED: To provide an antimony-containing aqueous solution treatment process by which antimony and/or its compound(s) can advancedly and efficiently be separated from an aqueous solution containing them while generating less waste. SOLUTION: This treatment process comprises: adding hydrochloric acid and a cationic surfactant to an aqueous solution containing antimony and/or its compound(s); and then, bubbling the aqueous solution to adsorb the antimony and/or its compound(s) on the surfaces of formed bubbles and to separate and remove the antimony and/or its compound(s) from the aqueous solution.
