description | The invention relates to the field of preparation of high-purity aluminum ammonium sulfate, in particular to a method for preparing a high-purity aluminum ammonium sulfate crystal by efficiently removing impurities from an aluminum ammonium sulfate crude solution. A crude aluminum ammonium sulfate solution extracted from aluminum-containing solid wastes such as red mud, fly ash and brown aluminum oxide fly ash is taken as a raw material, sulfosalicylic acid or ammonium citrate and glycolic acid are added as chelating agents, and stable macromolecular groups with electronegativity in an aqueous solution are formed by combining with impurities such as Fe < 3 + > and Ti < 4 + > in the solution, so that precipitation in the crystallization process of the aluminum ammonium sulfate is avoided, and the quality of the aluminum ammonium sulfate is improved. Therefore, the purpose of efficiently removing impurities to prepare high-purity aluminum ammonium sulfate is achieved. According to the method, the crystallizatio |
