Abstract
An object of the present invention is to provide a method of recovering a high-purity cerium compound from a solution containing cerium in a short time in a high yield, and more specifically, is to provide a method for recovering cerium as ammonium cerium (IV) nitrate from an acidic aqueous solution containing cerium, such as a waste liquid resulting from etching. The present invention relates to a process for producing ammonium cerium (IV) nitrate from an acidic aqueous solution containing at least trivalent cerium, tetravalent cerium, ammonium ions, and nitric acid, which is characterized in that the acidic aqueous solution contains a metal having an oxidation potential as measured at a pH of 2 or lower of 0.7 to 1.6V, and that the nitric acid concentration of this acidic aqueous solution is increased to thereby precipitate ammonium cerium (IV) nitrate crystals.
