摘要

To provide a purification method for a nickel-containing aqueous solution that reduces the nickel concentration of an aqueous solution containing nickel, and a compound having an ability to form a complex with nickel.SOLUTION: Inorganic sulfide, a polyamine having 3 to 8 nitrogen atoms, and an alkaline earth metal compound are added to an aqueous solution containing nickel and a compound having an ability to form a complex with nickel; and then, an inorganic flocculant is added thereto, the content of the inorganic flocculant is equal to or higher than the content of the compound having an ability to form a complex with nickel; after that, solid matter is removed therefrom.SELECTED DRAWING: None
